Q:
A) 64000 liters | B) 56000 liters |
C) 78000 liters | D) 60000 liters |
Answer: B) 56000 liters
Explanation:
Explanation:
Let x liter be the per day filling and v litr be the capacity of the reservoir, then
90x + v = 40000 * 90 -----(1)
60x + v= 32000 * 60 ------(2)
solving eq.(1) and (2) , we get
x = 56000
Hence , 56000 liters per day can be used without the failure of supply.
