A can do a work in 24 days and B in 32 days. If they work together and get Rs. 5600 for the work, what is B's share?
A. Rs. 3000
B. Rs. 3200
C. Rs. 2800
D. Rs. 2400
Answer: Option D
Solution (By JKSSB Mock Tests)
Ratio of time taken by A : B = 24 : 32 = 3 : 4. Ratio of efficiency of A : B = 4 : 3. Total ratio parts = 4 + 3 = 7. B's share = (3 / 7) * 5600 = 3 * 800 = Rs. 2400.
