Step-by-step explanation:

Given

Sum of the age of P and Q is 64 years.

The sum of age of P and R is 82 years.

Age of Q is half of the age of R.

To Find

Age of P

Solution

 \sf \: P +  Q  = 64 \:  \:  \:  \:  \:  -  -  -  - (1)

 \sf \: P  +  R  = 82 \:  \:  \:  \:  \:  -  -  -  - (2)

 \sf  \:   Q   =   \dfrac{    R  }{2  } \:  \:  \:  \:  \:  -  -  -  - (3)

Now In Equation (1)

 \sf \: P +  Q  = 64

\sf \: P = 64   -    Q

Putting the Value of P in Equation (2)

\sf \:  64   -    Q    +  R  = 82

\sf \:       R  = 82 - 64  +   Q

\sf \:       R  = 18  +   Q

Putting the Value of R Equation (3).

 \sf  \:   Q   =   \dfrac{    18  +   Q   }{2  }

\sf  \:  2 Q   =     18  +   Q

\sf  \:  2 Q   -  Q  =     18

\sf  \:    Q  =     18

Putting the Value of Q in P= 64 -Q.

\sf  \: P= 64 -18

\sf  \: P= 46

Hence the age of P is 46 year's.
