Answer 1

Steps: 3 Marks
Answer: 1 Mark

Let x and y be the number of stamps Sonia and Surjeet have respectively.

At the end of one month,

Ratio of the stamps of Sonia to Surjeet
= x : y = 89 : 93

$\frac{x}{y}=\frac{89}{93}$

$x=y.\frac{89}{93}$

Given: y = 2325

$x=2325\times \frac{89}{93}$

$x=\frac{2325\times 89}{93}=2225$

Hence Sonia has 2225 stamps.
