Question

two third of a tank can be filled by a tap in 2 hours and 30 minutes. how much of the tank will be filled in 45 minutes

Answer 1

> 1/5 of tank is filled in 45 min

➝ Correct Question:

• two third of a tank can be filled by a tap in 2 hours and 30 minutes. how much of the tank will be filled in 45 minutes

➝ Solution:

• it is given that ,

two third of a tank can be filled by a tap in 2 hours and 30 minutes

therefore,

= 2/3 of tank = 2 hour 30 min

= 2/3 of tank = 2x60 min + 30 min

= 2/3 of tank = 120 min + 30 min

= 2/3 of tank = 150 min

so,

1 min = 2/(3x150) of tank

now,

45 min = (2x45)/(3x150)

= (2 x 9)/(3 x 30)

= (2 x 3)/(3 x 10)

= 2/10

= 1/5

Hence, 1/5 of tank is filled in 45 min
