There are two filling pipes A and B. If A fills bottom 3/4th tank and B fills the rest tank, then they can fill the tank in 18 minutes. If B fills bottom 3/4th tank and A fills the rest tank, then they can fill the tank in 22 minutes. What is the time taken by both the pipes to fill the tank together?
Correct
Let A can fill complete tank in x minutes, then 3/4 in 3/4 * x minutes
Let B can fill tank in y minutes, so 1/4 in 1/4 * x minutes
So from given information:
3x/4 + y/4 = 18
and x/4 + 3y/4 = 22
Solve both the equations, x = 16, y = 24
So together they complete 1/16 + 1/24 = 5/48 tank in 1 minute or whole tank in 48/5 minutes

A boat can cover 24 km against the current of the stream in 4 hours and can cover 32 km along the current in 2 hours. How long will it take to go 5 km in still water?
Correct
Upstream speed = 24/4 = 6 km/hr
Upstream speed = 32/2 = 16 km/hr
So speed of boat in still water = 1/2 (6+16) = 11 km/hr
So time taken to travel 5km in still water = 5/11 hours
Incorrect
Upstream speed = 24/4 = 6 km/hr
Upstream speed = 32/2 = 16 km/hr
So speed of boat in still water = 1/2 (6+16) = 11 km/hr

At simple interest, an amount increases by 60% in 5 years. What will be the compound interest obtained on Rs 25,000 after 2 years at same rate percent per annum?
Correct
Is x is principal amount, SI = 60% of x
SO 60% of x = x*5*r/100

Correct
Rs 450 = 15 kg of wheat
20 kg of wheat = 11 kg of rice
30 kg of rice = 18 kg of pulses
16 kg of pulses = 25 kg of barley
22 kg of barley = x
