Question

a takes 6 days less than B to do a particular work if a and b work together they will finish the work in 4 days find the time taken by both of them if they work separately ​

Answer 1

Step-by-step explanation:

B take work is =1/x

A take work is=1/x-6

A+B=1/4

Sub value of A and B

1/x-6+1/x=1/4

Take lcm and simplify we will get

4x+4x-24=x2-6x

X2-8x+24-6x=0

X2-14x+24=0

(X-12) (x-2)

X=12 or x=2

We will take x=12

A=1/x-6

Sub x=12

A=6 and b=12
