Directions (1-4): What value will come in place of the question-mark (?) in the following questions?

(1) 7
(2) 6
(3) 10
(4) 15
(5) None of these

Directions (5-7): What approximate value will come in place of question-mark (?) in the following questions?

5. 226•007 + 258•982 + 274•98 – 420•003 – 22•969 = ?
(1) 272
(2) 242
(3) 260
(4) 317
(5) 365

6. 27% of 406 + 22% of 1125 = ?
(1) 440
(2) 466
(3) 334
(4) 358
(5) 318

Directions (8-10): Find out the wrong number in the following number series.

8. 110, 156, 210, 272, 342, 424
(1) 424
(2) 210
(3) 272
(4) 342
(5) None of these

9. 35, 110, 335, 710, 1285, 1910
(1) 110
(2) 335
(3) 710
(4) 1285
(5) None of these

10. 15, 42, 167, 512, 1239, 2570, 4767
(1) 42
(2) 167
(3) 512
(4) 1239
(5) None of these

1. (2)

2. (3)

3. (2)

4. (2)

5. (4)

6. (4)

7. (2)

8. (1)
The series is (10)^2+10, (12)^2+12, (14)^2+14, (16)^2+16, (18)^2+18, (20)^2+20
So the number should be 420 in place of 424.
