A, B and C can do a work in 8, 10 and 12 days, respectively. After completing the work together, they received ₹5,550. What is the share of B (in ₹) in the amount received?

1,800

A = 8 days, B = 10 days, C = 12 days,

Adding all the Efficiencies = A + B + C = 15x + 12x + 10x = 37

⇒ 37x = Rs. 5550

⇒  x = \(\frac{5550}{37}\) = 150.

⇒ B's share is = efficiency x 150 = 12 x 150 = Rs. 1800.
