Question

A mother and her two son got a room constructed for rupees 60,000 .The elder son contributed 3/8 of his mother's contribution while the younger son contributes 1/2 of his mother's share.How much do the three contribute individually?​

Answer 1

Answer:

Mother's Contribution = 32000 Rs.

Elder Son's Contribution = 3×32000/8 = 12000 Rs.

Younger Son's Contribution = 32000/2 = 16000 Rs.

Step-by-step explanation:

Let mother's share be x Rs.

then, elder son's share= 3x/8

& younger son's contribution = 1x/2 = x/2

So, x + 3x/8 + x/2 = 60000

15x/8 = 60000

15x = 480000

x = 32000 Rs.

Mother's Contribution = 32000 Rs.

Elder Son's Contribution = 3×32000/8 = 12000 Rs.

Younger Son's Contribution = 32000/2 = 16000 Rs.
