Answer 2

Answer:

$2550 \: litres$

Step-by-step explanation:

Water used every day = 150 litres

Water used for 7 days = 150 × 7

= 1050 litres

Water remaining in the water tank after 7 days = 1500 litres

Quantity of water in the tank before using it = Water remaining + Water used

= 1500 + 1050

= 2550 litres
