Question

255 members of an apartment building required 160 litre of water per head per day if the tank measuring 24m 15m and 5m is completely filled with water then for how many days will the water in the tank last be sufficient to the tank last be sufficient ​

Answer 1

Step-by-step explanation:

No. of members = 255

Water required per head per day = 160 litres.

Therefore, water required for 255 members per head per day = 255 x 160

= 40800 litres.

Volume of water in the tank = volume of tank = 24 m x 15 m x 5 m

= 2400 cm x 1500 cm x 5 00 cm

= 3600000 x 500 cubic cm

=$\frac{3600000 \times 500}{1000} \\</p><p>= 3600 \times 500 = 1800000\: litres$

Water sufficient for no. Of days = $\frac{ 1800000}{40800} =44.. 11\approx 44$

Thus the water in the tank will be sufficient for approximately 44 days.
