Question

Forty-five percent of what number is 22.5? A. 10.125 B. 100 C. 50 D. 30

Answer 1

Look at the answers and be logical, try rounding up so instead of 45% try 50% now 22.5 would be half the number, have a look at the answers and see what is closest to double 22.5. C looks reasonable. Hope I helped, have a nice day :)

Answer 2

C. Is The Answer You’re Looking For.

Half Of 50 Is 25, And 22.5 Is Close To 25. So, The Answer Must Be C.
