Given:

रहेमान च्या 3 वर्षापूर्वीच्या वयाची व्यस्त आणि 5 वर्षानंतरच्या वयाची व्यस्त यांची बेरीज 1/3 आहे.

The sum of the reciprocals of Rehman's age (in years ) 3 year ago and 5 year from now is 1/3

To find:

तर रेहमान चे आजचे वय किती?

His present age

Solution:

Let "x" years represents the present age of Rehman.

Then,

3 years ago, Rehman's age was = (x - 3) years

5 years hence, Rehman's age will be =  (x + 5) years

As per the information given in the question, we can form the following equation as:

\frac{1}{(x - 3)} + \frac{1}{(x + 5)}  = \frac{1}{3}

\implies \frac{x + 5 + x - 3}{(x-3)(x+5)} =  \frac{1}{3}

\implies \frac{2x + 2}{(x-3)(x+5)} =  \frac{1}{3}

\implies 6(x + 1) = (x-3)(x+5)  

\implies x^2 + 2x - 15 = 6x + 6

\implies x^2 - 4x - 21 = 0

\implies  x^2 - 7x + 3x - 21 = 0

\implies  x(x - 7) + 3(x - 7) = 0

\implies  (x - 7) (x + 3) = 0

\implies x - 7 = 0 \:or\: x + 3 = 0

\implies x =  7\:or\: - 3

since age cannot be negative

\implies \bold{x = 7}

Thus, the present age of Rehman is → 7 years.
