Question

The total weight of Santino, Rico and Bong is 112 kg. Their weights are in the ratio 3:1:4. What is Santino’s weight? How much heavier is Bong than Rico?

Answer 1

Answer:

let the ratio's be 3x, 1x, 4x

ATQ-

3x+1x+4x =112kg

8x = 112

x = 112/8

x= 14

now,

santino = 3 * 14 = 42kg

rico = 1 * 14 = 14kg

bong = 4 * 14 = 56 kg

bong heavier than rico = 56-14

= 42kg
