19 is the correct answer

Answer 2

Hello !

• 12 :

`12 + 2 * 12 + 5 = 41 \\e62`

• 15 :

`15 + 2 * 15 + 5 = 50 \\e62`

• 18 :

`18 + 2 * 18 \ + 5 = 59 \\e62`

• 19 :

`19 + 2 *19 + 5 = 62`

The value that holds true for the equation is 19. So, Jenny is 19 years old and her mother is 43 years old.

Have a nice day ;)
