the ratio of manju's income to her expenditure is 5:1 . what is the percentage of money spent by her

Answer»

ong>Answer:

LET the salary of Rohan is Rs 100

Given the expenditure and saving RATIO of 5:1

Then expenditure =65×100=6500 Rs

And savings =61×100=6100 Rs

If his salary increased by 25% then NEW salary =100+25=125 Rs

Given that after salary increased the savings increased 15 %

Then new saving =6100×100115=6115 Rs

So the expenditure after salary increased=125−6115=6750−115=6635 Rs

Then INCREASE expenditure after salary increased=6635−6500=6135 Rs

Then % increase expenditure after salary increased=6135×5006×100=27 %
