Two taps running together can fill a tank in 3 113 hours. If one tap takes 3 hours more than the other to fill the tank, then how much time will each tap take to fill the tank?
Let time taken by 1st tap to fill the tank = x hrs
Time taken by 2nd tap = (x+3) hrs
Together they fill in 3113=4013hrs
So, 1st tap fill the tank in 5 hrs
and 2nd tap fill the tank in 5 + 3 = 8 hrs
