Question

Rahim works in a software company and earns Rs. 75,000/- per month. He saves Rs. 28,000/- per month from his earnings. Find the ratio of 

i) His savings to his income

ii) His income to his expenditure 

iii) His savings to his expenditure

Answer 1

Given Rahim’s monthly income = Rs. 75000 

Monthly savings = Rs. 28000 

Monthly expenditure = income – savings

 = 75000 – 28000 = 47,000/- 

i) Ratio of savings to income = 28000 : 75000 

To convert the ratio into the simplest form divide each term by their HCF is 1000 

= 28000 ÷ 1000 : 75000 ÷ 1000 (divide by 1000) 

= 28 : 75 

Required ratio of savings to income = 28 : 75

ii) Ratio of income to expenditure = 75000 : 47000 

To convert the ratio into the simplest form divide each term by their HCF is 1000 = 75000 ÷ 1000 : 47000 ÷ 1000 (divide by 1000) 

= 75 : 47 

Required ratio of income to expenditure = 75 : 47

iii) Ratio of savings to expenditure = 28000 : 47000 

To convert the ratio into the simplest form divide each term by their HCF is 1000 = 28000 ÷ 1000 : 47000 ÷ 1000 (divide by 1000) 

= 28 : 47 

Required ratio of savings to expenditure = 28 : 47
