Question

Vu is three times as old as Wu. In 25 years Wu will be twice as old as Vu. How old is Vu now?

Answer 1

Answer: Vu is 15 years old now.

Step-by-step explanation:

Let present age of WU be x.

Then, the present age of Vu = 3x

Also, After 25 years

Age of Wu = x+25

According to the question:

$(x+25)=2(3x)\\\\\Rightarrow\ x+25=6x\\\\\Rightarrow\5x=25\\\\\Rightarrow\ x=5$

Present age of Vu = 3(5) = 15

Hence, Vu is 15 years old now.
