Riddle

A student was once given a simple task to accomplish. He was given 6 numbers: 1, 10, 20, 30, 40, and 80, and was told to sum them together to be equal to 100. At last, he was able to accomplish this task. How did he do it?

Choose an answer

A.He used a calculator error
B.He rounded the numbers
C.He added them in a different order
D.He read 10 and 80 backward to give him 01 and 08 respectively. So, 1 + 01 + 20 + 30 + 40 + 08 = 100.
Hint: It's a 10-word phrase with 43 letters, starting with "H".

Answer

He read 10 and 80 backward to give him 01 and 08 respectively. So, 1 + 01 + 20 + 30 + 40 + 08 = 100.

Why this is the answer

Flipping 10 and 80 upside down/backward turns them into 01 and 08, and 1+01+20+30+40+08 sums exactly to 100.
