Solve the following questions and find the value that will come in place of ‘?’.

1. (0.2)^48 ÷ (0.04)^16 * (0.008)^2 = (0.2)?

21
22
23
24
25
Option B
(0.2)^48 ÷ (0.04)^16 * (0.008)^2 = (0.2)?

(0.2)^48 /(0.2)^32 * (0.2)^3 * 2 = (0.2)?

(0.2)^48 – 32 + 6 = (0.2)?

? = 22

2. 80 % of 605 – 14.285 % of 420 + √1444 * √16 = ? * √576

24
Option E
80 % of 605 – 14.285 % of 420 + √1444 * √16 = ? * √576

484 – 60 + 152 = ? * 24

24 = ?

3. 52 * 8 – 90 % of 40 = ? + 18 * √841

-123
-124
-125
-146
-142
Option E
52 * 8 – 90 % of 40 = ? + 18 * √841

416 – 36 = ? + 522

? = -142

4. 120% of 700 + 60% of 385 – ? = 37 * 19

142
236
328
368
354
Option D

120% of700 + 60% of 385 – ? = 37 * 19

840 + 231 – ? = 703

? = 368

5. 12.5% of 560 + 83.33% of 138 + 62.5% of 552 = ?

458
530
450
440
238
Option B
12.5% of 560 + 83.33% of 138 + 62.5% of 552 = ?

1/8 * 560 + 5/6 * 138 + 5/8 * 552 = ?

70 + 115 + 345 = ?

530 = ?

6. 13^2 + 15^2 + 11^2 =?
234
125
656
515
575
Option D
?= 169 + 225 + 121 =515

7. Simplify :43 * 37 + 54 * 46 =?

4055
4085
4015
4075
4065
Option D
?= (40 + 3)(40 – 3) + (50 + 4)(50 – 4)

= 1600 – 9 + 2500 – 16

= 4075

8. Simplify:2.25 * 16 + 5.25 * 8 =? + 83
-5
-15
-25
-35
-10
Option A
? + 75 = 36 + 42 = 78

=> ? = 78 – 83 = -5

9. 15% of 1080 + 25% of? = 182
85
80
70
82
60
Option B
162 + 25% of ? = 182

=> 25% of ? = 182 – 162 = 20

=> ? = 20 * 100/25 = 80

10. 144 * 36 – 100 * ? = -1000
61.84
66.84
65.84

Option A
144 * 36 – 100 *? =-1000

=> 100 x ? = 144*36 + 1000

= 5184 + 1000 = 6184

=> ? = 61.84
