She'll have 17 with a remainder, just divide 139 by 8.
The unknown number . . . . . (z)
The sum of the unknown number and 22 . . . . . (z + 22)
The sum of the unknown number and 22
divided by the same unknown number . . . . . . . (z + 22) / z
You said that quotient is 12. (z + 22) / z = 12
Multiply each side by 'z' : (z + 22) = 12 z
Subtract 'z' from each side: 22 = 11 z
Divide each side by 11 : 2 = z .
To convert hour into minute: (No. of hour × 60) minutes
So, 2/5 hours = (2/5 × 60) minutes = (120/5) minutes = 24 minutes

Answer:
A. 282
Step-by-step explanation:
A trick I know is if you add all the digits of the number and they add up to a multiple of 3, it is divisible by 3.
282:
2 + 8 + 2 = 12
187:
1 + 8 + 7 = 16
385:
3 + 8 + 5 = 16
412:
4 + 1 + 2 = 7
