Hint: Here, in this question, we are going to use the fact that if we are asked to find the age of a person after y years then we have to add y to his present age and if, like in this question, we are given to find the age y years ago, then we have to deduct or subtract y from the present age. So, here we must subtract 3 from x+2 in order to get our answer.
Complete step-by-step answer:
In this given question, we are provided that Yamuna’s present age is x+2 years. We are asked to determine Yamuna’s age 3 years ago.
Now, let us take Yamuna’s age 3 years ago to be z.
So, at present her age should be z+3 years.
Now, it is given that her present age is x+2 years.
So, we get z+3=x+2……….. (1.1)
Equation 1.1 gives us that z is equal to x-1.
As, z is the age of Yamuna 3 years ago, from equation 1.2, we get Yamuna’s age three years ago as x-1 years.
Therefore, the required answer to the given question is x-1 years.
Note: In this sort of question, we must be careful to add the years to the present age if it is given to determine the age after some years and to subtract the years from the present age if it is to determine the age before some years or some years ago.
