Question

Nora is twice old as Raj, and half as old as Ethan. In 22 years time, Ethan will be twice old as Raj. Find Nora present age?

Answer 1

Assume Raj's current age is A. According to the given information, Nora is twice as old as Raj, so her current age is 2A. Nora is also half as old as Ethan, which means Ethan's current age is 2 * 2A = 4A. Therefore, Nora's present age is 22 years.

Answer 2

22

Explanation:

Let's assume Raj's current age is R.

According to the given information, Nora is twice as old as Raj, so her current age is 2R.

Nora is also half as old as Ethan, which means Ethan's current age is 2 * 2R = 4R.

In 22 years, Ethan will be twice as old as Raj, so we can set up the equation:

4R + 22 = 2(R + 22)

Let's solve this equation to find the value of R:

4R + 22 = 2R + 44

4R - 2R = 44 - 22

2R = 22

R = 11

Now that we know Raj's current age is 11, we can find Nora's age:

Nora's current age = 2R = 2 * 11 = 22

Therefore, Nora's present age is 22 years.
