Question

Ram works in an office and gets $₹1500$ per month$.$ He saves $₹120$ per month$.$ Find the ratio of his expenditure to his pay$.$

Answer 1

Step $1:$ To find out the ratio of expenditure to pay

Given Ram's earnings savings per month $=$$₹1500$

Ram's savings per month $=$$₹120$

Ram's expenditure $=1500-120$

$=₹1,380$

Step $2:$ Now find the ratio

Required Ratio $=$$₹1380$ $:$ $₹1500$

Step $3:$ Convert the ratio into fraction into its simplest form

$₹1380$ $:$ $₹1500$ can be written as

$=\frac{1380}{1500},$ divide the numerator and denominator by $10$

$=\frac{138}{150}$ $,$ now divide the numerator and denominator by $6$

$=\frac{138/6}{150/6}$

$=\frac{23}{25}$

Hence, the ratio of expenditure to pay is $23:25$
