Let, the number be "x"
According to the question,
12 % of x = 48
(12 / 100) * x = 48
.12 * x = 48
x = 48 / .12
x = 400
So, 48% of 400 is 48.

Let the number be "x"
According to the question,
175% of 76 = x
(175 / 100) * 76 = x
1.75 * 76 = x
133 = x
So, 175% of 76 is 133.
3>
Let the % be "x"
According to the question,
x% of 16 = 20
(x / 100) * 16 = 20
x / 100 = 20 / 16
x = (20 / 16) * 100
x = 125
So, 125% of 16 is 20.
4>
Let the % be "x"
According to the question,
x% of 200 = 96
(x / 100) * 200 = 96
x * 2 = 96
x = 96 / 2
x = 48
So, 48% of 200 is 96.
