22. When Ria and Flora compared the amounts of money in their savings accounts, they found that their savings were in the ratio $5: 3$. Then Ria took 160 euros from her savings to buy a tablet. The ratio of their savings then changed to $3: 5$. How many euros did Ria have before buying the tablet?
A 192
B 200
C 250
D 400
E 420
22. C The original ratio of the amounts of money in Ria's and Flora's savings accounts was $5: 3=25$ : 15. After Ria withdrew 160 euros, the ratio changed to $3: 5=9: 15$. Since Flora's savings have not changed, the 160 euros Ria withdrew represented $\frac{(25-9)}{25}=\frac{16}{25}$ of her original savings. Therefore 10 euros represented $\frac{1}{25}$ of her original savings and hence she originally had 250 euros.
