Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 750.
Given:
Samir and Puneet can complete the same work in 10 days and 15 days
Total amount = Rs 4500
Work completed in 5 days
Calculations :
Let the total work be LCM (10,15) = 30 units
Samir efficiency = 30/10 = 3 units
Puneet efficiency = 30/15 = 2 units
Total one-day efficiency of Samir and Puneet = 5 units
Samir and Puneet worked for 5 days = 25 units
Remaining work = 5 units
Ashok worked for 2 days = 5/2 = 2.5 units
Amount given for 1 unit of work = 4500/30 = 150
Amount given to Ashok = 150 × 5 = Rs.750
