Raman can do a work in 5 days, Jatin can do the same work in 7 days and Sachin can do the same work in 9 days. If they do the same work together and they are paid Rs. 2860, then what is the share of Raman?
Raman can do 1/5, Jatin can do 1/7 and Sachin can do 1/9 of the work in 1 dayRatio of their work in 1 day = 1/5 : 1/7 : 1/9
⇒ Ratio is 63 : 45 : 35 And the amount paid to them also will be in the same ratio.
⇒ Raman’s share {(63)/(63 + 45 + 35)} × 2860
∴ Raman’s share is Rs. 1260
