Explanation / Answer

7) Pages read on friday = 40 = (1 - 1/2 - 1/3)x = x/6

Thus, total pages, x = 240 pages

Pages read on wed = 1/3 * 240 = 80

10) Let, number be x

x/2 + 3 = x - 4

x/2 = 7

x = 14

12) sqrt(22 - 3p) is real

thus, 22 - 3p >= 0

p >= 22/3

13) set of negative numbers

14) 2, 3, -9

4th term: -8

5th term: -8 * -3 = 24

6th term: 25

7th term: 25 * -3 = -75

15)Increase in salary = 160000 - 80000 = 80000

Increase percent = 100%
