Question

12 Men or 15 women 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:

42 days will be required to do same work because the no. of people's is reduced by half so the work will be increased by ×2

Answer 2

Answer:

12 men = 15 women ⇒ 1 man

Men = 15/12  women

Men =  5/4  

15 women can finish the work by 21 days

6 men = 6*5/4  women

6 men = 15/2

6 men and 10 women = 15/2+10=35/2  

women can finish the work= 21*15*2/35  = 18 days.
