Answer:
Step-by-step explanation:
Equations are solved in pic given below.
Let, 1 man's 1 day's work = x and 1 boy's 1 day's work = y.
Then, 12x + 16y = 1/5
and 13x + 24y = 1/4
Solving these two equations, we get : x = 1/100 and y =1/200
=>(7 men + 10 boy)'s 1 day's work = =>7(1/100) + 10(1/200)
=>7/100 + 10/200
=>14/200 + 10/200
=>24/200
=>3/25
Thus, 7 men and 10 boys can do
the work in 25/3 days.
