plz ans my question ​

Answer 1

Step-by-step explanation:

3 men + 2 boys complete work in 6 days.

=> 6 men + 4 boys can complete in 3 days.

We further know 5 men + 7 boys can complete work in 3 days.

=> 1 man = 3 boys

=> 11 boys can complete work in 6 days.

Now 2 men and 5 boys means 11 boys.

=> They complete work in 6 days.

:-)

6 days

18m+12b can do in 1day

15m+21b can do in 1day

3m=9 b or 1m=3b

(18×3)+12 boys can do in 1 day or

66 boys do it in 1 day

1boy’s 1 day's work=1/66

2m or (2×3 boys) +5 boys 1 day's work=11/66

So 11 boys can do that work in=6 days
