Directions (Q. 1–5): What value should come in the place of question mark (?) in the following questions?

1. (-6 + 9 * ? + 16 + 9)/(14 * 14 - 156) = 7
1) 36
2) 29
3) 28
4) 27
5) 31

2. sqroot(?)/sqroot(441) = sqroot(529)/11.5
1) 1336
2) 1824
3) 1221
4) 1764
5) 1290

3. 1.33 × 6 – 2.85 ÷ ? = 6.48
1) 2.6
2) 3.9
3) 1.9
4) 5.1
5) 1.7

4. (11*11)/(7*7) - (36*?)/(7*7) + (18*18)/(7*7) = 1
1) 11
2) 13
3) 9
4) 19
5) 17

5. cuberoot(658503) + cuberoot(2197) = ?
1) 72
2) 100
3) 109
4) 94
5) 106

6. [cuberoot(11)]^1/2 / (1331)^(-1/2) * [cuberoot(11)]^2 = [cuberoot(11)]^?
1) 4
2) 5
3) 8
4) 7
5) 6

7. 9 6/17 * 3 4/27 * 9/5 + 8 4/5 * 9 6/11 = ?
1) 127
2) 132
3) 144
4) 147
5) 137

8. 9/11 of 517 / 12 = ? / 212
1) 7473
2) 7743
3) 7437
4) 7483
5) 7347

9. 24089.58 – 14199.08 – 2329.50 = ?
1) 7561
2) 7651
3) 7516
4) 7568
5) 7615

10. sqroot(16641) × sqroot(1024) ÷ sqroot(4096) = ?
1) 62.5
2) 60.5
3) 64.5
4) 76.5
5) 79.5

1. 2
– 6 + 9× ? + 25 = 7 (196 – 156)
19 + 9 × ? = 7 × 40
9 × ? = 261
? = 29

2. 4
sqroot(?) = 23/11.5 * 21 = 42
? = 1764

3. 3
2.85 ÷ ? = 7.98 – 6.48
? = 1.9

4. 1
121/49 + 324/49 - 1 = (36 * ?)/49
396 = 36 × ?
? = 11

5. 2
? = 87 + 13 = 100

6. 4
[cuberoot(11)]^? = (11)^1/6 / (11)^(-3/2) * 11^(2/3)
(11)^?/3 = (11)^(1/6 + 3/2 + 2/3)
?/3 = (1 + 9 + 4)/6
? = 7

7. 5
? = 159/17 * 85/27 * 9/5 + 44/5 * 105/11
= 137

8. 1
? / 212 = 9/11 * 517/12
? = 9/11 * 517/12 * 212
? = 7473

9. 1
? = 7561

10. 3
? = 129 * 32 / 64
= 129/2 = 64.5
