Question

reena is ten years older than babu. next year she will be twice as old as him. how old are they now?​

Answer 1

To Find:-

Present ages of Reena and Babu

Given:-

Reena is 10 years older than Babu

Solution:-

Let Babu's age be x

Let Reena's age be x + 10

Next year,

➝ Age of Babu = x + 1

➝ Age of Reena = x + 11

According to the question,we have,

x + 11 = 2(x + 1)

x + 11 = 2x + 2

x - 2x = 2 - 11

-x = -9

x = 9

So, Age of Babu = 9 years.

Now, Age of Reena = x + 10

= 9 + 10

= 19 years.

Therefore,

➝ Age of Babu = 9 years.

➝ Age of Reena = 19 years.
