If the work done by 8 men and 4 boys in 1 days is 7 times the work done by 1 man and 1 boy, then compare the work done by 1 man and 1 boy in 1 days ?

- 1
- 2
- 3
- 1/2
Correct Option: C
Here, a1 = 8, b1 = 4, a2 = 1, b2 = 1 and n = 7
∴ Work done by 1 man/Work done by 1 boy = (nb2 - b1)/(a1 - na2)
= (7 x 1 - 4) / (8 - 7 x 1)
= 3
