Money saved by elder son = Rs. 20
Percentage of money spend by elder son = 80%
Percentage of money saved by elder son 20%
Therefore, 20% = Rs. 20
Money spent = 80% = Rs. 80
Total money given to the elder son = Rs. 20 + Rs. 80 = Rs. 100
Let the total money divided between the two sons be Rs. x.
The elder son gets 80% of total money given.
So, 80% of Rs. x = Rs. 100
Rs. x = Rs. 125
Let father's monthly income be Rs. y.
Money given to sons = 1% of Father's monthly income
1% of y = Rs. 125
y = Rs. 125 × 100
y = Rs. 12500
Ans. = Father's monthly income is Rs. 12500.
