The prices of oven A and B after 20 yrs of installation is $3600 and $4800 respectively.
Price of oven A and B after 25 yrs from installation is $1800 and $2400 respectively.
The value has halved every 5 yrs.
From 20 yrs after installation to 5 yrs after installation, the gap year is 15 yrs.
Which is multiplied by 2 three times to reach 5 yrs after installation.
Difference in values between two ovens = ($4800-$3600) = $1200.
$1200 * (2*2*2) = $9600.
