ANSWERS
1. (3): (440/100) X 50 = 220

2. (5):
80.80 – 69.84 + 92.33 = 42.98 + x
173.13 – 112.82 = x
x = 60.31

3. (2):
29^2 – 25^2 = x^2 + 16
841 – 625 = (x)^2 + 16
216 = x2 + 16
x2 = 200
x = 10

4. (4):
50.05% of 200 + 300% of 500 = x + √10000
50.05/100 * 200 + 300/100 * 500 = x + 100
100.1 + 1500 = x + 100
x = 1500.10

5. (4):
8/17 * 68/24 * 72/40 = x
12/5 = x
x = 2.4

6.  (2):
75/100 * 25 + 50/100 * 240 = x/100 * 600
75/4 + 120 = x/100 * 600
75/4 + 120 = 6x
(75 + 480)/4 = 6x
555/4 = 6x
x = 555/24

7. (1):
3√729 - 3√512 = 3√x
9 - 8 = 3√x
x = 1

8. (5):

9. (4):
4/15 * 150/100 * 880 = x
4 * 880 = x
x = 352

10. (5):
130/100 * 120 + x/100 * 175 = 420
156 + 7x/4 = 420
(624 + 7x)/4 = 420
7x = 1680 - 624
x = 1056/7
