Detailed Solution
Download Solution PDFGiven:-
A father gives 8% of his monthly income to both his sons as pocket money
The elder son gets 85% of the total amount given to both sons.
He spends 90% of the amount and saves Rs. 17.
Calculation:-
Let 100M represent the monthly income of the father.
Then part of the salary was given to the two sons as pocket money
⇒ 100M × 8/100 = 8M.
Now The elder son gets 85% of the total amount given to both sons.
⇒ (8M × 85)/100 ....... (1)
The second part of the question,
The elder son spends 90% of the amount and saves Rs. 17.
which means
⇒ Elder son pocket money × 10% = 17
⇒ Elder son pocket money = 170Rs
Comparing the Elder son's pocket money from the equation,
⇒ (8M × 85)/100 = 170
⇒ M = 200/8
The monthly income of the father. = 100M = (200/8) × 100 = 2500 "
∴ The required answer is 2500.
