Answer 2

Answer:

4 hours

Step-by-step explanation:

B= v+m

V takes 8 more hrs than v+m (v= 8+v+m)

B take 8 hrs less than vishnu alone so we can write vishnu take 8 more hrs than bramha (v=8+B).

V+m=B so √8x8 =8

B = 8 , v+m = 8 together 8/2 4 hrs answer

Many place you have seen Answer 6hrs only when it's 18 hrs less is given in question in last line ..
