Question

A's age is half that of B's age. When B's age doubles, what will be the ratio of
B's age to that of A's age

​

Answer 1

Answer:same as earlier

Step-by-step explanation:

A:B=1:2

If B age double then,

A:B=2:4=1:2

Answer 2

$\large\red{\underline{\underline{\bf{\blue{Answer}}}}}$

Ratio of ages 2:1

$\large\red{\underline{\underline{\bf{\blue{Given}}}}}$

• A's age = B's age / 2

$\large\red{\underline{\underline{\bf{\blue{To\:Find}}}}}$

• Ratio of B's age to A's age

$\large\red{\underline{\underline{\bf{\blue{Solution}}}}}$

Let age of B = x years

Then,

According to Question :-

A's age = x/2 years

When B's age doubles then,

B = 2x years

Then,

A's age = 2x/2 = x years

Now,

Ratio of B's age to A's age is

$= > \frac{2x}{x}$

=> 2:1

Hence,

Ratio of B's age to A's age is 2:1
