Correct Answer :D - 5 Days
Detailed Text Solution
Efficiency ratio A to B = 3 : 7
Total work = (3 + 7) × 10½
= 10 × (21/2)
= 105
Work done by both in 8 days = (3 + 7) × 8
= 10 × 8
= 80
Remaining work = 105 − 80
= 25
60% of the remaining work = 25 × (60/100)
= 15
60% of the remaining work A will complete in = 15 / 3
= 5 days
