Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 17640.
Let Vipul's monthly income be x
Spent on rent = 30% of x = 0.30x
Remaining amount = x - 0.30x = 0.70x
Amount spent on groceries = 60% of 0.70x = 0.42x
Remaining amount = 0.70x - 0.42x = 0.28x
Amount spent on others = 40% of 0.28x = 0.112x
Savings = 0.28x - 0.112x = 0.168x
So, 0.168x = ₹7056
⇒ x = 7056/0.168 = 42000
⇒ 0.42x = 0.42 × 42000 = ₹17640
Therefore, Vipul spends ₹17640 on groceries.
