Question

The ratio of income to expenditure of A is 11:7 and that of B is 13:9.find the ratio of their savings

Answer 1

Let the income of A =11x

expenditure of A=7X

then Saving of A =(income - expenditure)
=11x-7x
=4x


Income of B=13x

expenditure of B=9x

Saving of B=13x- 9x
=4x

Ratio of the income of A and B
=4x/4x
=1

A and b have the same amount of saving.
