Question

19 .150 liters of water used form a water tank every day. after 7 days there are 1500 liters of water remaining. how much water was there in the water tank in the beginning?​

Answer 1

Answer:

Given that :

150 litres of water used from a water tank every day.

And after 7 days 1500 lites of water is remaining.

So, Water used in 1 day = 150 litres

then, water used in 7 days = 150 × 7 = 1050 litres

And remaining water after 7 days = 1500 litres ( that means the water is unused)

Total water in the water tank at the beginning = 1050 + 1500 = 2550 litres.

So, 2550 litres of water was there at the beginning.

Hope you understand it
