Finding wages of each worker A, B and C undertake to do a piece of work for Rs.1950. A work for 8 days, B for 9 days and C for 12 days to complete the work. If their daily wages are in the ratio of 3:5:4 , What does C get ?

Daily wages are in the ratio 3 : 5 : 4

Working days of A, B and C = 8, 9 and 12

So the wages they get will be in ratio

$3 \times 8 : 5 \times 9: 4 \times 12$

= 24 : 45 : 48

Share of C

= $\frac{48}{(24+45+48)} \times 1950 = 800$
