Question

The age of Sunil is 48 years. His age is 3 years less than 3 times the age of his daughter. Find the age of his daughter.

Answer 1

Hint: In this problem the age of Sunil is given to us and some relation is given between the age of Sunil and his daughter. So let the age of Sunil’s daughter be some variable and use the relations provided in the question to formulate this required variable.

Complete step-by-step answer:
Let the age of his daughter be x years.
Given, Sunil’s age = 48 years.
Now it is given that Sunil's age is 3 years less than the 3 times of the age of the daughter.
Now, construct the linear equation according to this information.
Therefore three times x minus three is equal to 48.
$ \Rightarrow 3x - 3 = 48$
Now simplify this equation we have,
$ \Rightarrow 3x = 48 + 3 = 51$
Now divide by 3 in above equation we have,
\[ \Rightarrow x = \dfrac{{51}}{3} = 17\] Years.
So, the required age of the daughter is 17 years.

Note: Whenever we face such types of problems the key point is simply to use the information provided in the question in order to formulate equations with the assumed variable and then using these equations to get the required age. This will always help in getting the track to reach the answer.
