Three years ago, poorvi was thrice as old as his sister reena. After three years poorvi will be twice as old as reena. What is t

blagie [28]

The present Age of Reena is 6 years.

Let us assume that the Present Age of Reena is 'x' years, so the present Age of Poorvi is 2x years than Reena's.

Three years ago, Reena's Age was (x-3) years.

And Poorvi's Age was (2x-3) years.

So, by using the above knowledge, we can drive an equation and find the value of x from it:

2x - 3=3 (x - 3)

2x - 3 = 3x - 9

-3 + 9 = 3x -2x

After solving the above equation, it gives us the value of x, that is,

x = 6

Now we put this value of x in Reena's Age,

Reena's present Age is x = 6 years

And Poorvi's present Age is 2x of Reena's Age,

Poorvi’s Age = 2 * 6 years

Poorvi's Age = 12 years

It satisfies the condition that her present age of is twice as her sister, Reena.
