Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ₹4,000.
Ram spends:
30% on food → 0.30X
10% on house rent → 0.10X
7% on entertainment → 0.07X
6% on conveyance → 0.06X
Total expenditure = 0.30X + 0.10X + 0.07X + 0.06X = 0.53X
After all expenses, his savings are ₹1,880, so:
⇒ X − 0.53X = 1,880
⇒ 0.47X = 1,880
⇒ X = 1,880/0.47
⇒ X = 4,000
