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.
