A tank contain 30 lter more water when it is 50 % full than in 40% full. What is the capacity of barrel ?​

Answer 1

Answer:

Step-by-step explanation:

When the barrel is 30% empty, it is actually 70% full.

So, the difference in the quantity when it is 70% filled to, when it is 30% filled is 50 litres

= (70%-30%)=50

= 40% of the barrel is 50lt.

100% of the barrel is..

100×50÷40= 125lt.
