Question

A water tank contains 1000 litres. Due to leakage in the tanker, the water level
decreases at the rate of 5 litres per hour. How much water will be left in the tanker
after 7 hours?
​

Answer 1

Answer: 965 L

Step-by-step explanation:

Initial quantity of Water Tank,

V_i= 100L

Rate of loss of water from tank,

R = 5L/h

Time at which we need to observe quantity of water in tank if initial quantity is at t =0 is 7hours .

Then,

Amount of water lost in 7 h

= 7 * R = 7*5 = 35L

Amount of water left in the tanker after 7 hours, is

Initial quantity - lost water = 1000-35 = 965 L.

Hence, Required answer is 965 L.
