Quantity A:

A alone can complete the work in = 10 days

∴ A’s 1 day’s work = 1/10

B alone can complete the work in = 12 days

∴ B’s 1 day’s work = 1/12

C alone can complete the work in = 15 days

∴ C’s 1 day’s work = 1/15

∴ Ratio of work of A, B and C

⇒ (1/10) ? (1/12) ? (1/15)

⇒ 60 × 1/10 ? 60 × 1/12 ? 60 × 1/15

⇒ 6 ? 5 ? 4

Total earning = Rs. 4500

∴ Share of C,

⇒ 4500 × [4/(6 + 5 + 4)]

⇒ 4500 × 4/15

⇒ Rs. 1200

Quantity B:

Rs. 1200

∴ Quantity A = Quantity B
