Correct Answer: INR 2,500


Solution : Let the father’s monthly income be $x$.
Money saved by elder son = INR 17
Money given to the sons = 8% of $x$ = 0.08$x$
Money given to elder brother = 85% of 0.08$x$ = 0.068$x$
Percentage of money spent by him = 90%
Percentage of money saved by him = 10%
Money saved by him = 10% of 0.068$x$ = 0.0068$x$
Also, 0.0068$x$ = 17
⇒ $x$ = 2500
Hence, the correct answer is INR 2,500.
