Question

Seventy-five postcards cost $₹18.75.$ How many postcards can be bought for $₹25$?

Answer 1

Given

Number of postcards bought for $₹18.75=75$

Number of postcards bought for $₹1=\frac{75}{18.75}$

$=4$

Now, the number of postcards for $₹25=25\times 4$

$=100$

Hence, the required solution is $100$
