Question

The total mass of Faizal, John and Raju is 154.2 kg. John is 10.48 kg

heavier than Raju and 9.23 kg heavier than Faizal. Find Raju's mass.

Answer 1

R = 47.49 kg

Explanation:

To find answer, I will put things in terms of Raju's mass

J = R + 10.48

J - 9.23 = F or R + 10.48 - 9.23 = F

F + J + R = 154.2

(R + 10.48- 9.23) + (R+10.48 ) + R = 154.2

3R = 142.47

R=47.49 kg
