G₁ can do a piece of work alone in 20 days, G₂ can do the same piece of work alone in 40 days, while G₃ can do it alone in 60 days. They worked together and completed the work. If the combined share received by G₁ and G₂ is ₹2,700, then what is the total amount received by all the 3 workers taken together?

₹3,300

G1 = 20 days, G2 = 40 days, G3 = 60 days,

⇒ Combined share received by G1 + G2 = Rs. 2700.

⇒ (6 + 3)x = 2700

⇒ 9x = 2700

⇒ x = 300,

⇒ Total amount they all got = (6 + 3 + 2) x 300 = 11 x 300 = Rs. 3300.
