My dear Aspirants,
My heartfelt deep apologies for pausing this work of Aptitude. On this auspicious day of Vijayadhasami, a day of good start, let us restart and resume the work more energetically and vigorously. Let us have a good number of questions on this wonderful day. We have successfully completed 300 questions as of today and the past 9 weeks posts of our blog. Let's wait for our next milestone achievement of 100 posts and 1000 questions soon!!! :) Keep Supporting us!!! HAPPY VIJAYADHASAMI!!
If Neena says "Anitha's father Raman is the only son of my father-in-law Mahipal", then how is Bindhu, who is the sister of Anitha, related to Mahipal?
Only son of Neena's Father in Law Mahipal is Neena's Husband.
So, Raman is Neena's husband and Anitha & Bindhu are his daughters.
Thus, Bindhu is the grand - daughter of Mahipal.
A man leaves for his office from his house. He walks towards East. After moving a distance of 20m, he turns South and walks 10m. Then he walks 35m towards the West and further 5m towards the North. He then turns towards East and walks 15m. What is the straight distance in metres between his initial and final positions?
Hence, (x+42) / 7 = 9; x = 21

A third of Arul's mark in Mathematics exceeds a half of his marks in English by 30. If he got 240 marks in the two subjects together, how many marks did he get in English?
Let the Math and English marks be x and y respectively.
1/3x -1/2y = 30
(2x - 3y) / 6 = 30
2x - 3y = 180 ----- (1)
x + y = 240 -------- (2)
Solving 1 and 2,
x = 180.
So, English Marks y = 240 - 180 = 60.
If 4/5 of an estate be worth Rs. 16,800, then the value of 3/7 of the estate is _______.
4/5x = 16800
x = 16800 * 5/4 = 21000
3/7x = 3/7 * 21000 = 9000
The sum of three consecutive multiples of 3 is 72. What is the largest number?
Let the three numbers be x, 3x+3 and 3x+6 respectively.
3x + 3x+3 + 3x+6 = 72
9x + 9 = 72
9x = 63
x=7
So, the largest number is 3x + 6 = 21 + 6 = 27.
My brother is three years elder to me. My father was 28 years of age when my sister was born while my mother was 26 years of age when I was born. If my sister was 4 years of age when my brother was born, then what was the age of my father and mother respectively when my brother was born?
Clearly, my brother was 3 years before when I was born and 4 years after my Sister was born. So, father's age when brother was born = 28 + 4 = 32 years and
mother's age when brother was born = 26 - 3 = 23 years
A salesman's commission is 5% on all sales upto Rs. 10,000 and 4% on all sales exceeding this. He remits Rs. 31,100 to his parent company after deducting his commission. Find the total sales.
Let the total sales be .
Total Sales - Commission = 31100
x - 5% of 10000 + 4% of (x-10000) = 31100
x - [(5/100 * 10000) + (4/100 (x-10000)) ]= 31100
x - 500 - x/25 + 400 = 31100
x - x/25 = 31200
( 25x - x ) / 25 = 31200
24x = 780000
x = 32,500
After getting two successive discounts, a shirt with a list price of Rs. 150 is available at Rs. 105. If the second discount is 12.5%, find the first discount.
Let the first discount be x%.
Then 87.5% of (100-x)% of 150 = 105
87.5/100 * (100-x / 100) * 150 = 105
100 - x = (105 * 100 * 100) / (87.5*150)
100 - x = 80
x = 20
The first discount is 20%.
A, B and C enter into partnership. A invests 3 times as much as B invests and B invests two third of what C invests. At the end of the year, the profit earned is Rs. 6600. What is the share of B?
Let C's capital be x. Then B's capital is 2/3x.
A's capital is 3 * 2/3x = 2x
Ratio of capitals = 2 : 2/3 : 1 = 6 : 2 : 3
So, B's share = 2/ 11 * 6600 = Rs. 1200.
If 15 men, working 9 hours a day, can reap a field in 16 days. In how many days will 18 men reap the field, working 8 hours a day?
Let the number of days be x.
More men, less days ----- Indirect Proportion
Less hours per day, more days ----- Indirect Proportion
Men :: Hours :: (Days)
18 : 15 :: 8 : 9 :: (16 : x)
18 * 8 * x = 15 * 9 * 16
x = 15 * 9 * 16 / ( 18 * 8)
x = 15 days.
A man can row upstream at 7kmph and downstream at 10kmph. Find man's rate in still water and rate of current.
Rate in still water = 1/2 (10 + 7) = 17/2 = 8.5kmph
Rate of current = 1/2 ( 10 - 7) = 3/2 = 1.5kmph
The perimeters of two squares are 40cm and 32cm. Find the perimeter of a third square whose area is equal to the difference of the areas of the two squares.
Side of 1st square = 40/4 = 10cm
Side of 2nd square = 32/4 = 8cm
Area of third square = 100 - 64 = 36cm²
Side of the third square = √36 = 6cm
Perimeter of the third square = 6 * 4 = 24cm.
The movements of the man is shown in the above figure. Clearly, DC = AB + EF. F is also in the line of A. AF = (BC - DE) = 5m.
So, the man is 5m away from his initial position.
The positions of how many digits in the number 321465987 will remain same when the digits are arranged in Ascending Order?
Original Number - 3 2 1 4 6 5 9 8 7
Ascending Order - 1 2 3 4 5 6 7 8 9
Clearly, the positions of 2, 4, 8 remain unaltered.
Aman is 16th from the left end in a row of boys and Vivek is 18th from the right end. Gagan is 11th from Aman towards the right and 3rd from Vivek towards the right end. How many boys are there in the row?
Vivek is 18th from the right end and Gagan is 3rd to the right of Vivek. So, Gagan is 15th from the right end. Thus, there are 15 boys to the left of Aman, 10 boys between Aman and Gagan and 14 boys to the left of Gagan.
So, the number of boys in the row = 15 + 1 + 10 + 1 + 14 = 41.
In a Cricket match, five batsmen A, B, C, D and E scored an average of 36 runs. D scored 5 more runs than E. E scored 8 fewer than A. B scored as many as D and E combined and B & C scored 107 runs between them. How many runs did E score?
Total runs scored = 36 * 5 = 180
Let the runs scored by E be x.
Runs scored by D = x + 5
Runs scored by A = x + 8 ( E = A - 8 )
Runs scored by B = 2x + 5 (B = D + E )
Runs scored by C = 107 - B = 107 - 2x - 5 = 102 - 2x
So, total runs, (x + 8) + (2x + 5 ) + (102 - 2x) + (x+5) + x = 180
3x + 120 = 180
3x = 60
x = 20
Runs scored by E is 20.
Which would be the proper order of the following in Ascending Order?
Trillion, Thousand, Billion, Hundred, Million
Hundred, Thousand, Million, Billion, Trillion.
Find the relationship. (27, 9, 54), (42, 14, 84), (?, 7, 42)
We have, (27 + 54) / 9 = 9 and (42+84) / 14 = 9.Hence, (x+42) / 7 = 9; x = 21

My brother is three years elder to me. My father was 28 years of age when my sister was born while my mother was 26 years of age when I was born. If my sister was 4 years of age when my brother was born, then what was the age of my father and mother respectively when my brother was born?
Clearly, my brother was 3 years before when I was born and 4 years after my Sister was born. So, father's age when brother was born = 28 + 4 = 32 years and
mother's age when brother was born = 26 - 3 = 23 years
A salesman's commission is 5% on all sales upto Rs. 10,000 and 4% on all sales exceeding this. He remits Rs. 31,100 to his parent company after deducting his commission. Find the total sales.
Let the total sales be .
Total Sales - Commission = 31100
x - 5% of 10000 + 4% of (x-10000) = 31100
x - [(5/100 * 10000) + (4/100 (x-10000)) ]= 31100
x - 500 - x/25 + 400 = 31100
x - x/25 = 31200
( 25x - x ) / 25 = 31200
24x = 780000
x = 32,500
After getting two successive discounts, a shirt with a list price of Rs. 150 is available at Rs. 105. If the second discount is 12.5%, find the first discount.
Let the first discount be x%.
Then 87.5% of (100-x)% of 150 = 105
87.5/100 * (100-x / 100) * 150 = 105
100 - x = (105 * 100 * 100) / (87.5*150)
100 - x = 80
x = 20
The first discount is 20%.
A, B and C enter into partnership. A invests 3 times as much as B invests and B invests two third of what C invests. At the end of the year, the profit earned is Rs. 6600. What is the share of B?
Let C's capital be x. Then B's capital is 2/3x.
A's capital is 3 * 2/3x = 2x
Ratio of capitals = 2 : 2/3 : 1 = 6 : 2 : 3
So, B's share = 2/ 11 * 6600 = Rs. 1200.
If 15 men, working 9 hours a day, can reap a field in 16 days. In how many days will 18 men reap the field, working 8 hours a day?
