TCS Company Numerical Ability Area and Volume

Q). 2 cm of rain has fallen on a sq.km of land. Assuming that 50 % of the raindrops could have been collected and contained in a pool having a 100 m x 10 m base, by what level could the water level in the pool have increased ?

1) 15 m
2) 20 m
3) 10 m
4) 25 m

Read Solution (Total 3)

area of pool base = 100 m * 10 m = 1000 m^2

volume of rain = (1 km)^2 * 2 cm = 1000*1000*2/100 = 20000 m^3

50% of rain collected = 20000*50/100 = 10000 m^3

so, level of pool increased = volume of rain collected / area of pool base

= 10000/1000 = 10 m

3) 10 m
