Ram takes 6 days less than Bhagat to finish a piece
of work. If both of them together can finish the

can finish the work?​

Answer 1

ram =6

bhagat =12

Lcm =12 =total work

perday work ram=2unit per day

bhagat=1 unit per day

total work per day =2+1=3

3×4= 12

bhagat alone complete in 12 days

Answer 2

Answer:

• pls mark as brainliest

Step-by-step explanation:

B alone finish work in x days

A alone work in x/x -6

A one day works= 1/(x-6) and B one day works = 1/x

A+B one day work = 1/4

so, 1/(x-6) + 1/x =1/4

x+x-6/x(x-6) = 1/4,

2x-6/x(x-6) =1/4

4(2x-6) = x(x-6),

8x-24 = xsq - 6x,

x sq -14x +24 = 0

ans : x = 12 or 2
