### Q1

What should come in place of question mark (?) in the following questions? 628.88 – 410.25 + 153.05 = ?
A. 371.68 B. 56.58 C. 317.68 D. 65.58

A
? = 628.88 – 410.25 + 153.05
= 628.88 + 153.05 – 410.25
= 371.68

### Q2

What value should come in place of the question mark (?) in the following questions? 4 x 306 + 5 x 204 - 6 x 187 = ? x 17 x 6
A. 11 B. 12 C. 15 D. 17

A
4 x 17 x 18 + 5 x 17 x 12 - 6 x 17 x 11 = ? x 17 x 6
72 + 60 - 66 = ? x 6
x = 11

### Q3

What should come in place of question mark (?) in the following question? 162.05 × 126.03 ÷ 62.87 + 178.44 - 294.77 = ?
A. 315 B. 295 C. 154 D. 207

D
162.05 × 126.03 ÷ 62.87 + 178.44 - 294.77 = ?
The expression can be approximated to
162 × 126 ÷ 63 + 178 - 295
= (162 × 18 × 7) ÷ 63 + 178 - 295
= 324 + 178 - 295 = 207

### Q4

What will come in the place of question mark (?) in the following question? 689.812 + 129.11 × 30.12 – 79.84 =?
A. 4380 B. 4440 C. 4400 D. 4480

D
689.812 + 129.11 × 30.12 – 79.84
= 690 + 129 × 30 - 80
= 690 + 3870 – 80 = 4480

### Q5

A. 1280 B. 1180 C. 1130 D. 1230

D
? = 600 + 670 - 140
= 1130 (approx)
