Question

12 men and 15 woman can do a piece of work in 21 days. find the number of days required to complete the same work by 6 men and 10 women​

Answer 1

Answer:

days=18

Step-by-step explanation:

12men*21days=15 women *21days

men /women=15*21/12*2

men/women=5/4

men=5

women=4

then,put value of men and women in the equation....

6 men+10women*days=12men*21

(6*5+10*4)days=12*5*21

(30+40)days=60*21

days=60*21/70

days=18 days
