Question

the pencil and the laptop computer are both tools that help writers accomplish their tasks. Follow the clues below to find the year each of these amazing instrument was invented. Their difference is 192. Their sum is 3782.

Answer 1

What you do is divide the sum by 2. You will come out with and answer of 1891. Now, to figure out the years they were invented you take the difference of 192 and divide that in half also. It will come out to 96. Now, you subtract 1891 by 96 and that is the year the pencil was invented (1795=pencil) now with the other half (1891) you add on 96 and you’ll come out with the answer of 1987.

Pencil=1795
Laptop computer=1987.

Hope this helped!
