A certain amount of money is divided among x, y and z. If x receives 25% more than y and y receives 25% less than x. then x : y : z is equal to
1). 14:12:13
2). 15:12:16
3). 10:9:12
4). 12:10:11
Amount received by y = rs 100.
Amount received by x = rs 125.
Amount received by z,
$\frac{100\times100}{75}$ = rs $\frac{400}{3}$
Required ratio = 100 : 125 : $\frac{400}{3}$
= 15 : 12 : 16
