Question

A batch of bottles were packed in 25 boxes with 12 bottles in each box. If the same batch is packed using 20 bottles in each box, 15 boxes are required.

• A. True
• B. False

Answer 1

The correct option is A

True

The number of bottles and the number of boxes are in inverse proportion.

AB = constant
$A_1\times B_1$ = $A_2\times B_2$

Suppose the required number of boxes is $x$

Then, $\frac{25}{x}$ = $\frac{20}{12}$

Number of boxes, x = $\frac{(25\times 12)}{20}=15$
