A solution leaks out of a jar at the rate of p liters for every q hours. If the solution costs 10 dollars per liter, what is the cost, in dollars, of the amount of the solution that will leak out in r hours?
(A) pr/(10q)
(B) 10q/(pr)
(C) 10p/(qr)
(D) 10pr/q
(E) 10qr/p
Leaking rate p liters for every q hoursi.e. in 1 hour, Leakage = p/q litres
i.e. in r hour, Leakage = r*(p/q) litres
Cost = $10 per litre
i.e. Cost of Total Leakage = 10*r*(p/q)
Answer: Option D
