10. 8.03 x 12.02 + 25% of ? = 37.5% of 191.8 + 370.5 ÷ 7

Directions:(1-6) What value should come in place of the questions mark (?) in the following questions?

##### 1. Question

529 ÷ 46 x 7.4 + 83 – 251 = ?

Ans: 5
? = 23÷46 x 7.4 + 512 – 251
= 0.5 x 7.4 + 512 – 251
= 3.7 + 512 – 251
= 264.7
##### 2. Question

(3 – √5)2 = ? – √80 – √20

Ans: 2
5 + 9 – 6√5 = ? – 4√5 – 2√5
=> ? = 14
##### 3. Question

(16 x 4)3 ÷ (4)5 x (2 x 8)2 = (4)?

Ans: 4
(4)? = (64)3 ÷ (4)5 x (16)2
=> (4)? = (64)3 ÷ (4)5 x (16)2
= 49 ÷ 45 x 44 = 48
=> ? = 8
##### 4. Question

(363/2 x 3434/3 x 322/5) / (283 x 272/3)

Ans: 1
(363/2 x 3434/3 x 322/5) / (283 x 272/3)
= [(62)3/2 x (73)4/3 x (25)2/5] /[283 x (33)2/3]
=(63 x 74 x 22) / (283 x 32)
= (24 x 7 x 4/64) = 21/2 = 10.5
##### 5. Question

38% of 850 + 39% of 1100 – 32% of 1725 = ? x 10

Ans: 3
? x 10 = 850 x 0.38 + 1100 x 0.39 – 1725 x 0.32 = 323 + 429 – 552 = 200=> ? = 20
##### 6. Question

√? ÷ 39 X 156 – 195 + 232 X 1.5 = 381

Ans: 2
√? ÷ 39 X 156 – 195 + 348 = 381
=> √? ÷ 39 X 156 = 228
√? = 228 x 39/156 = 57
=> ? = 572 = 3249

Directions:(7-10) What approximate value will come in place of question mark (?) in the following questions? (You are not expected to calculate the exact value.)

##### 7. Question

6999.94 – 3501.01 – 499.09 + 1499.2 + 500.3 = ? – 1999.91 – 4000.3 + 999.97

Ans: 3
≈7000-3500-500+1500+500 = ? -2000-4000+1000
=> 5000 = ? – 5000
=> ? = 10000
##### 8. Question

√290 x √170 + √98 x √72 = ?

Ans: 5
? = 17 x 13 + 7√2 x 6√2
= 221 + 84 = 305
##### 9. Question

? = 59.99 x (7.03 x 8.02 + 13.03 x 9.01 – √1596)

Ans: 2
? ≈ 60 x (7×8 + 13×9 – 40)
= 60 x 133 = 7980 ≈ 8000
##### 10. Question

8.03 x 12.02 + 25% of ? = 37.5% of 191.8 + 370.5 ÷ 7

Ans: 1
8×12 + 25% of ? = 3/8 x 192 + 371 ÷ 7
=> 96 + 25% of ? = 72 + 53
=> 25% of ? = 29
=> ? = 116 ≈ 115
