Question

The number of 25 paise coins in Rs. 100 is ________________

Answer 1

Hint: We can find the required number of 25 paise coins in Rs 100 by converting Rs. 100 into paise first.

Complete step-by-step solution -
In general $Rs.1=100\,paise$
As we know there are 100 paise in Rs. 1
So in Rs.100 number of paise is
$\Rightarrow Rs.100=100\times 100\,paise$
$\Rightarrow Rs.100=10000\,paise$
Hence number of 25 paise coins in 10000 paise is
$\dfrac{10000}{25}=400$
Hence there are 400 coins of 25 paise in Rs.100.

Note: While doing this question we need to be careful about conversion. Either we will change Rs. to paise or paise to Rs. Number of coins is a unitless quantity so the numerator and denominator should be in the same unit while finding the number of coins.
