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 incomeii) His income to his expenditure iii) His savings to his expenditure

Answer»

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
