Answer 2

Given,

'My' age is X years.

The grandmother's age = 10 more than 4 times of 'my' age

To find,

The grandmother's age in years.

Solution,

The grandmother's age will be (10+4X) years.

According to the question,

'My' age is X years.

The grandmother's age = 10 more than 4 times of 'my' age

Let's take the grandmother's age to be y years.

Now, we will the age of grandmother into an algebraic expression by changing the different terms, if possible, into their mathematical signs.

So,

'More than' is to be replaced by + and 'times' is to be replaced by ×.

Now,

y = 10 + (4×'my' age)

y = (10+4X) years

Hence, the grandmother's age is (10+4X) years.
