Question

$235$ liters of water is filled in an empty tank in the first hour and $200$ liters in the second. If $150$ liters of water leaks out, what quantity of water will be left in the tank?

• A. $435L$
• B. $235L$
• C. $585L$
• D. $285L$

Answer 1

The correct option is D $285L$

Quantity of water filled in the first hour $=235L$
Quantity of water filled in the second hour $=200L$
To calculate the total quantity of water filled in the tank, we add $235L$ and $200L.$

Total quantity of water in the tank $=435L$
Quantity of water lost due to leakage $=150L$
To calculate the quantity of water left after leakage, we subtract the quantity of water lost from the total quantity of water.

Therefore, $285L$ of water will be left in the tank.
