Here are answers:
1. 40% of 50 is 20
2. 20% of 50=10
3. 25% percent of 36 is 9
4. 25% of 500 is 125
5. 12.5% of 88=11
6. 65 is 62.5% of 104
(ie. 62.5% of 104 is 65)
(Its very easy, if [(x%) of y =z] then x, y and z are related to each other by (x*y)/100=z. You know values of 2 variables, find the 3rd.)

Question 1
40% of X = 20
40/100 x X = 20
2/5 x X = 20
X = 100/2 = 50
Question 2
20/100 x 50 = 1/5 x 50 = 10
Question 3
(1/4).X = 125
X = 4 x 125 = 500
Question 4
(25/100).X = 125
(1/4).X = 125
X = 500
Question 5
(12.5/100) x 88 = (1 / 8) x 88 = 11
Question 6
(65/104) x 100% = (0.625) x 100% = 62.5%

1. 40% of what no is 20
let the no be x;
40% of x = 20;
40x/100 = 20
40x = 100*20
40x = 2000;
x = 2000/40;
x = 50;
the number therefore is 50;
2. 20% of 50 = 20/100 * 50/1;
.2*50=10
20% of 50 = 10;
what percentage of 36 is 9?
x% of 36 = 9
x/100 * 36/1 = 9;
36x/100 = 9;
36x = 900;
x = 25;
25% of what no is 125?
25/100 * x = 125;
25x/100 = 125;
25x = 12500;
x = 500;
25% of 500 is 125;
12.5% of 88 = 12.5/100 * 88;
12.5*88/100 = 11
12.5% of 88 = 11
65 is what percent of 104
x% of 104 = 65
104x/100 = 64
104x = 6400
x = 61.53
hope its all right
