Correct Answer: INR 130
Solution : Average daily expenditure of Mohan over 4 days = INR 120 Sum of expenditure over 4 days = 120 × 4 = 480 Expenditure on the first 3 days = INR 60, INR 150 and INR 140 Let $x$ be the expenditure on the $4^{\text {th }}$ day. So, $x$ + 60 + 150 + 140 = 480 ⇒ $x$ = 480 – 350 = 130 Hence, the correct answer is INR 130.
