A alone can finish a work in 2 days, while B alone can finish it in 3 days. if they work together to finish it, them out of total wages of ₹ 6000, what will be the 20% of A's share?
-
- ₹ 720
- ₹ 350
- ₹ 820
- ₹ 420
- None of the above
Correct Option: A
A's 1 day's work = 1/2
B's 1 day's work = 1/3
A's share : B's share = 1/2 : 1/3 = 3/6 : 2/6 = 3 : 2
A's share (3/5) x 6000 = 3 x 1200 = ₹ 3600
∴ 20% of A's share 3600 x (20/100) = ₹ 720
