Question

If 3men or 6 boys can finish a work in 20 days .then 6men and 8boys finish twice the work in

Answer 1

Answer:

The work can be completed in 20 days by 3 men or 6 boys.

Hence the capacity of 3 men = the capacity of 6 boys.

Hence if 6 men and 8 boys do the work together, than it is equivalent to,

6+8= 14 men

Now the work quantum = 3 *20 = 60

Hence if now equivalent to 10 men are doing the work, then

No. of days = 60/14 = 5 days and some minutes..
