Question

a container has 60 litres of oil it is kept under the hot sun due to which it expands by 15% then in the night 10% is lost due to leakage find the volume of oil left​

Answer 1

Step-by-step explanation:

Given :-

A container has 60 litres of oil it is kept under the hot sun due to which it expands by 15% then in the night 10% is lost due to leakage .

To find :-

Find the volume of oil left ?

Solution :-

Volume of the oil container = 60 litres

Expanding Percentage in day time

= 15% of the total volume

=> 15% of 60 litres

=> 15% × 60

=> (15/100)×60

=> (15×60)/100

=> 900/100

=> 9 litres

Increasing in day time = 9 litres

So Total volume of the oil container in day time

= 60+9

= 69 litres

Total volume of the oil container = 69 litres

Decreasing Percentage in night time

= 10% of the total volume

=> 10% of 69 litres

=> 10% × 69

=> (10/100)×69

=> (10×69)/100

=> 690/100

=> 6.9 litres

Decreasing in night time = 6.9 litres

So Total volume of the oil container in night time

= 69-6.9

= 62.1litres

Answer:-

The volume left in the oil container is

62.1 litres
