Question

3 men and 2 boys finished a works in 6days. 5 men and 7 boys finished the same work in 3 days. In how many days 2 men and 5 boys can complete this work ?

Answer 1

your answer

• 3m+2b=1/6
• 5m+7b=1/3
• solve these equations, we get
• m=3 and b=1
• putting the value of m and b in eqn 1st we get 66 works
• according to the question 2m+5b after calculating by value of m and b we get 6 efficiency.
• now divide to work by efficiency we get 6 days

6 Days
