6 boys and 8 girls can do job in 10 days , 26 boys & 48 women do work in 2 days. Find time taken by 15 boys and 20 girls to do same work ?

Correct Answer: 4 days

Explanation:

One day work of 6 boys and 8 girls is given as 6b + 8g = 1/10 -------->(I)


 



One day work of 26 boys and 48 women is given as 26b + 48w = 1/2 -------->(II)


 


Divide both sides by 2 in (I) and then multiply both sides by 5


Now we get, 15b + 20g = 1/4.


Therefore, 15 boys and 20 girls can do the same work in 4 days.
