What amount will B get paid?
Explanation:
Assume C can do x work in 1 day,
B can do 2x work in 1 day, and
A can do 4x work in 1 day.
Total work = 12(x + 2x + 4x) = 84x Now, A and B work for 8 days, therefore 8(2x + 4x) = 48x of work will be completed. B and C can do 3x work in 1 day.
So, the remaining 36x of work can be completed in 12 days.
A gets Rs. 2000 for his 32x of work.
B has done 40x of work.
So, B will get (2000 × 40)/32 = Rs. 2500.
Hence, option (b).
