If V1 : V2 = 1 : 2 and V1 + V2 = 147, then what is the value of V2 − V1?
Answer & explanation
Correct answer: option 4
If V1 : V2 = 1 : 2
V1 + V2 = 147,
then what is the value of V2 − V1.
Let the value of V1 and V2 = 1x and 2x
according to the question,
1x + 2x = 147
3x = 147
x = 49
V2 − V1 = 49 × 2 - 49 = 49
