Question

Annual income of rekha is 120000 and monthly income of reena is 12000 if monthly expenditure of both is 5000 then find the ratio of annual savings of re khatu annual savings of reena

Answer 1

Annual income of Rekha = 120,000

Her monthly expenditure = 5000

Then her yearly expenditure will be :-

$= 5000 \times 12$

$\color{hotpink}= 60,000$

Then her yearly savings will be :-

$\color{hotpink}= 60,000$

Monthly income of Reena = 12,000

Then her yearly income will be :-

$= 12000 \times 12$

$\color{hotpink} = 144,000$

Her monthly expenditure = 5000

Her annual expenditure = 60,000

Then , her yearly savings :-

$= 144000 - 60000$

$\color{hotpink}= 84,000$

Ratio of annual savings of Rekha to the annual savings of Reena :-

$= 60000 : 84000$

$= \frac{60000}{84000}$

$= \frac{60}{84}$

$= \frac{5}{7}$

$\color{hotpink} = 5 : 7$

Which means 5:7 is the ratio of their annual savings .

Therefore ratio of annual savings of Rekha to the annual savings of Reena = 5:7 .
