Question

Pamela is 12 years older than Jiri. The sum of their ages is 82 . What is Jiri's age?

Answer 1

Given

It is given that Pamela is 12 years older than Jiri.

The sum of their ages is 82.

Step-by-step explanation

Let the Pamela age be x.

Jiri age be y.

Then the equation formed is

`x=y+12`
`x+y=82`

Solve the above two equations and find x and y.

`\begin{gathered} y+12+y=82 \\ 2y=82-12 \\ 2y=70 \\ y=35 \end{gathered}`

Now find x,

`\begin{gathered} x+35=82 \\ x=82-35 \\ x=47 \end{gathered}`

Answer

Hence the Jiri's age is 35 years.
