Answer: Elder son: 12,000
Second son: 16,000
Youngest brother: 32,000
Step-by-step explanation: According to the given question.
The elder son contributed 3/8 of his youngest brother's contribution which means he had contributed (3/8) *x.
The second son contributed 1/2 of his youngest brother's share which means he had contributed (1/2) * x.
The sum of all three contributions = 60000
So,
x+(3/8)*x + (1/2)*x = 60000
The next step is to simplify the equation:-
8x + 3x + 4x = 480000
After adding all the terms:-
15x = 480000
Dividing both sides of the equation by 15:-
x= 480000/15
x= 32000
The youngest brother's contribution is 32000
Now We can able to find the contribution of each son:-
Youngest brother (x) = 32,000
Elder son = (3/8) * x
= (3/8) * 32,000 = 12,000
Second son = (1/2) * x
= (1/2) * 32,000 = 16,000
