Answer 2

Answer:

(a) 21

Step-by-step explanation:

Given:

42 mens can complete a work in 15 days

ie, 42 mens=15 days

then 30 mens can complete the same work in = ? days

ATQ:

if 42 mens can complete a work in 15 days

then 1 men can complete that work in= 42×15 days

So, 30 mens will complete the work in= 42×15/30 days

Therefore, required number of days is:

= 42×15/30

= 42/2

= 21 days.

hence, 30 mens will complete the same work in 21 days.

hope it helps :)
