How much money each of them got?

Question

642 is divided into three friends Raghav,Anil and Sobha . Anil gets 4/5 of amount that Raghav gets and Sobha got 45.5% of amount that Anil got . How much money did each of them got?

Answer 1

A + R + S = 642

A = (4/5)R = 0.8R

S = (0.455)A = (0.455)(4/5)R = 0.364R

0.8R + R + 0.364R = 642

2.164R = 642

2164R = 642000

R = 296.68

A = 237.34

S = 108
