Q. A, B and C can do a work in 20, 25 and 30 days respectively. They undertook to finish the work together for Rs. 2220, then the share of A exceeds that of B by ?

  • (A) Rs. 120
  • (B) Rs. 180
  • (C) Rs. 300
  • (D) Rs. 600
Correct Answer - Option(B)
Explanation by: Lalit Singh 
Ratio of share = Ratio of 1 day's work = 1/20 : 1/25 : 1/30 = 15 : 12 : 10
∴ A's share = Rs. 2220 x (15/37) = Rs. 900
B's share = Rs. 2220 x (12/37) = Rs. 720
∴ A's share exceeds B's share = Rs. 180
