A is 25% more efficient than B. If they working together can finish a work in 20 days, then in how many days can B alone finish it?
A. 40 days
B. 36 days
C. 45 days
D. 50 days
Answer: Option C
Solution (By JKSSB Mock Tests)
Let efficiency of B = 4, then efficiency of A = 5. Combined efficiency = 9 units/day. Total work = 20 * 9 = 180 units. Time taken by B alone = 180 / 4 = 45 days.
