Read Solution (Total 4)
-
- 1 day = 24 hrs,
let x be the amount of time completed.
so,time left=(24-x).
i.e.
(1/5)x=(24-x)
=>x=20.
so! time left is 24-20=4 hrs.
Ans:time is : x = 20 hrs =8pm. - 11 years agoHelpfull: Yes(29) No(2)
- 8pm
(1/5)x + x = 24hrs . from this we can calculate x (no. of hours completed out of 24 hrs.) - 11 years agoHelpfull: Yes(11) No(13)
- A day has 24 hrs,
let x be the amount of time left.
Therefore amount of time left=24-x
hence according to given condition,
x=1/5(24-x)
which gives x=4....therefore the current time is 12(night)-4=8pm
Hence according to the givin condition, - 11 years agoHelpfull: Yes(4) No(0)
- Solution is a) 8pm
because:
completed are "x" hours
left 1/5 of "x" hours
=> x+1/5x=24=12pm
=> 5/5x+1/5x=24
=> 6/5x=24
=> x=5/6*24
=> x=220/6=20=8pm - 9 years agoHelpfull: Yes(0) No(0)
