Question

Estimate: 11 is 50% of what number? A 20 B 40 C 60 D 5

Answer 1

Answer:

50% of a number means that we are taking half of a number.  Since 11 is 50% of a number that means that we need to multiply 11 by 2 to get the original number.  When we multiply 11 by 2 we get 22 and that is closest to option A which is 20.

Answer:  Option A, $20$
