Question

A tanker has the capacity to fill 30 buckets. How many buckets will be filled by the tanker if the capacity of tanker is reduced by 2/5 times?

• A. 10
• B. 15
• C. 8
• D. 12

Answer 1

The correct option is A 10

Capacity of tanker is reduced by $\frac{2}{5}times$
Capacity of the remaining tanker = $1-\frac{2}{5}=\frac{3}{5}$
Let the number of buckets to be filled be ${}^{\prime }{x}^{\prime }$.
By unitary method,
$\frac{30}{1}=\frac{x}{3/5}$
$x=\frac{30\times 3}{5}=18$
