Question 74
Anmol states, "18% of the first number is equivalent to 45% of the second number. What percentage of the second number does 63% of the first number represent?
Solution
Let the two numbers be Y and Z, such that
18% of Y = 45% of Z
Then, 63% of Y = ? % of Z
18% of Y = 45% Z
63% of Y = ? % of Z
∴ 18 x ? = 45 x 63
∴ ? = 45 x 63 = 157.5%
So answer is 157.5% of Z
