Question

The ratio of Sandy's savings to Sarah's savings is 2 : 5. If Sandy spends $\frac{1}{4}$
of her money, she will have $98 less than Sarah. How much is Sarah's savings?

Answer 1

let sandy and sarah have 2x and 5x savings respectively.

(cause the ratio of their saving is given as 2:5)

net amount left with Sandy=2x-2x/4

=3x/4

also

3x/4+98=5x

5x-3x/4=98

17x/4=98

x=392/17

therefore Sarah's saving is

5*392/17

=115.3
