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