Question

Hector's calculator is malfunctioning. If he puts in a problem that should equal 12,his calculator says 26.If he puts in a problem that should equal 15,his calculator says 32.If he puts in a problem that equals 100,his calculator says 202.What is his calculator doing to the answer each time?

Answer 1

Doubling the actual answer and increasing it by 2.

Explanation:

The calculator is returning 26, instead of 12. Note that 26 is 2 more than twice of 12.

i.e.

26 = 2(12) + 2

Calculator is returning 32 instead of 15. Here again we can note the same logic. 32 is 2 more than twice of 15.

i.e.

32 = 2(15) + 2

Calculator returns 202 instead of 100. Here again the same logic holds true.

i.e.

202 = 2(100) + 2

So, what the calculator is doing is:

Doubling the actual result and increasing it by 2.
