A man invested Rs. 14,400 in Rs. 100 shares of a company at 20% Premium. If the company declares 5% dividend at the end of the year, then how much does he get?

Number of shares = 14400/120 = 120

Face Value = Rs. 100 * 120 = Rs. 12000

Annual Income = 5/100 * 12000 = Rs. 600

Quants 22 - Boats and Streams
A man takes 3 hours 45 minutes to row a boat 15 km downstream of a river and 2 hours 30 minutes to cover a distance of 5 km upstream. Find the speed of the river current in km/hr. 
Rate downstream = 15/(3 3/4) = 15/(15/4) = 15 * (4/15) = 4 kmph
Rate upstream = 5/(2 1/2) = 5/(5/2) = 5 * (2/5) = 2 kmph
Speed of current = 1/2 ( 4-2 ) = 1/2 (2) = 1 kmph
