Let first second and third pipe fill the tank in x, y and z hrs respectively, According to question, x = y + 5 ......(i) y = z + 4 ......(ii)
and z = 1/(1/x+1/y) or z= xy/(x+y) .......(iii) Substituting value of y and and z from (i) and (ii) into (iii) x(x-5)/(x+x-5) = x-5-4 or x2-18x+5 = 0 or x = 3, 5 x = 3 is not possible as y = x- 5
So x = 15 hrs Ans
