Mohit and Rohit undertook a work for Rs. 6600. Mohit alone can do that work in 25 days. Rohit alone can do the same work in 30 days. They work together. What will be the difference in the amount (in Rs.) they receive?
Show answer & explanation
Correct answer: C
Explanation
Given:
Total amount = ₹6600
Mohit's time = 25 days
Rohit's time = 30 days
Mohit's efficiency = 1/25
Rohit's efficiency = 1/30
Ratio = 1/25 : 1/30 = 30 : 25 = 6 : 5
Total share = 6 + 5 = 11
Mohit's share = (6/11) × 6600 = 3600
Rohit's share = (5/11) × 6600 = 3000
Difference = 3600 − 3000 = ₹600
