Question

if 4 boys and 6 girls do work in 24 days then how many days will 6 boys and 18 girls do the work ​

Answer 1

Answer:

Work done by 4 boys =Work done by 6 girls.

Thus, potential of 4boys=potential of 6 girls.

Now, potential of 4 boys and 14 girls=potential of 6 girls + potential of 14 girls= potential of 20 girls.

Now, 6 girls can do the work in 40 days.

Thus, 1 day work of 6 girls =1/40

So, 1 day work of 1 girl=1/(40 x 6)

So, 1 day work of 1 girl=1/240

Thus, 1 girl can do the work in 240 days.

So, 20 girls can do it in 240/20 days or simply 12 days.

So,4 boys and 14 girls take to do the same work in 12 days.
