Question

12 years old Monika is three times as old as her sister Sheela . How old will monika be when she is twice as old as sheela​

Answer 1

Monika will be 8 years old.

Step-by-step explanation:

Step 1 look at the assumptions.

- Let us suppose that Sheela is x years old.

-While Monika is = 3 times as Sheela. Meaning, 3x

Step 2:

-If Monika is 3x, i.e. 12 years old.

Then x = 4

-How so?

-Its simple, you divide current age of 12 years by the value of how many times Monika is older.

so, 12/3 = 4

Step 3: So how old will Monika be when she is twice as old as Sheela?

If Monika is currently 4, when she will be double she will be 8 years old.
