Final answer:
To find the present age of Mr Sharma, set up and solve an equation based on the given information.
Step-by-step explanation:
To find the present age of Mr Sharma, we can solve the problem using algebraic equations.
Let's assume that the present age of Mr Sharma is represented by 'x'.
According to the problem, Mr Sharma is 5 times as old as his daughter. So, the present age of his daughter can be represented by 'x/5'.
In 8 years, Mr Sharma will be 20 years older than his daughter. So, his age after 8 years would be 'x + 8' and his daughter's age would be '(x/5) + 8'.
Using this information, we can create the equation 'x + 8 = (x/5) + 8 + 20'.
By simplifying and solving this equation, we can find the value of 'x', which represents Mr Sharma's present age.
