Question

If 10% of x is 20, what is 23% of x?

33

46

200

230

Answer 1

Since decimal form of 10% is 0.1 and 10% of x is 20,
0.1x = 20
x = 200
Since x = 200, 23% of x is:
(0.23)(200) = 46

The correct answer is 46.

Answer 2

10% = 10/100 = 0.1

20% = 23/100 = 0.23

0.1x = 20

x = 20/0.1 = 200

0.23x = 0.23 * 200 = 46  

23% of x = 46
