Water pool

Pool with volume 990hl completely filled, if water flows by one tap 8 hours and by second tap 6 hours. First tap give 10hl more than second per hour. How many hl flows in each of them in an hour?

Correct answer:

a =  75 hl/h
b =  65 hl/h

Step-by-step explanation:


990 = 8 a + 6b
a = 10 + b

990 = 8•a + 6•b
a = 10 + b

8a+6b = 990
a-b = 10

a = 75
b = 65
