Directions (1-5) :

36Â Ã· 18 Ã— 2 +âˆš3844Â  + 902Â Ã· x = 148

2 Ã— 2 + 62 + 902 Ã· x = 148

4 + 62 + 902/x = 148

902/x = 148 â€“ 66

x = 902/82 = 11

45% of 1600 + 30% of 450 â€“ 191 Ã— (x) = 91

720 + 135 â€“ 191 Ã— (x) = 91

x = (855-91)/191 = 4

32 % of 625 + 14 2/7 % of 1491 = (x)2Â –Â âˆš2304 + 20

(32/100) Ã— 625 + (1/7) of 1491 = x2Â – âˆš2304+20

200 + 213 = x2Â â€“ 48 + 20

413 = x2Â – 28

x = âˆš(413+28)

x = âˆš441 = 21

4284 Ã· 14 Ã— 3 â€“ {(20-5) x 4+ 306 Ã·3} = x

306 Ã— 3 â€“ {(15 Ã— 4 )+ 102 }= x

918 â€“ {60+102 } = x

x = 918 â€“ 162 = 756

âˆš5184 – âˆš1444 + ? = âˆš7225 + âˆš3136

72 – 38 + x = 85 + 56

x = 141 â€“ 34 = 107

Directions (6-10) :

12 * 0.5 +1 = 7

7 * 1 + 2 = 9

9 * 2 + 3 = 21

21 * 4 + 4 = 88

88 * 8 + 5 = 709

709 * 16 + 6 = 11350

15 +3 =18

18 â€“ 2 = 16

16 + 3 = 19

19 â€“ 2 = 17

17 + 3 = 20

20 â€“ 2 =18

5*1 + 1 = 6

6*2 â€“ 2 = 10

10*3 + 3 = 33

33*4 â€“ 4 = 128

128*5 + 5 = 645

645*6 â€“ 6 = 3864

There are two series is going on

First:

5 + 4 = 9

9 + 4 = 13

13 + 4 =17

Second:

12 – 3 = 9

9 â€“ 3 = 6
