Question

A takes 6 days less than the time taken by B to finish a piece of work. If both A and B together can finish it in 4 days, how many days will B take to finish the work?

Answer 1

Answer: B=5

Step-by-step explanation:

Well if we turn it into an equation, it says

A=B-6 (B-A=6)and A+B=4

SO by linear equations in two variables..... B - A - (A+B)= 6-2

B - A- A - B = 2

-2A = 2

A= -1(i know its not possible but thats how the question is)

Substitute this value in A+B=4

B= 5

Other way could've been to take A-B = 6 (but then b would come out to be negative so...)

Hope im right and it helped you, if not please let me know first before reporting so i could re-evaluate)
