Quants 5 - Calendar

What will be the day on October 15, 2020?

15th October 2020 = 2019 years + (Jan 1, 2020 to Oct 15, 2020)

Odd Days:

2000 = 0 Odd Days

19 Years = 4 Leap Years + 15 Ordinary Years

               = (4 * 2) + (15 * 1) = 23 days = 3 weeks + 2  day = 2 Odd Days

So, 0+2 = 2 Odd Days till 2019.

For 2020, counting days from Jan to Oct,

31 + 29 + 31 + 30 + 31 + 30 + 31 + 31 + 30 + 15 = 289 days = 41 weeks + 2 days = 2 Odd Days

So, 2 + 2 = 4 Odd Days

As Odd day 4 corresponds to Thursday, 15th October, 2020 is THURSDAY.

Quants 6 - Alligation

In what ratio must water be mixed with milk costing ₹12 per litre to obtain a mixture worth of ₹8 per litre?

Cost Price of water (c) = 0

Cost Price of milk (d) = 12

Mean price (m) = 8

Angle traced by minute hand in 60 minutes = 360˚.

Angle traced by it in 40 minutes = (360/60) * 40 = 240˚.

Required angle = 240˚ - 110˚ = 130˚.
