Question

5 men and 6 boys finish a piece of work in 4 days. 4 men and 3 boys can do it in 6 days. how many days 3 men and 6 boys will be able to finish​

Answer 1

Step-by-step explanation:

let's denote Men as m and Boys as b

(5m+6b)×4=(4m+3b)×6

=>20m+24b=24m+18h

=>4m=6b ....... i

now let the number of days for 3m and 6b be x

(5m+6b)×4=(3m+6b)×x

According to i

9m×4=7m=x

$x = 5 \frac{1}{7}$
