? ≈ 27 × 5 × | 145 | – 12 × 4 + 127 – 29 |
29 |
≈ 135 × 5 – 48 + 127 – 29
= 675 – 48 + 127 – 29
= 802 – 77 = 725
Hence, option B is correct.
20.01 × 1024 + 159 = ?2 + 536
20 × 1024 + 159 = ?2 + 536
20 × 32 + 159 = ?2 + 536
640 + 159 = ?2 + 536
799 – 536 = ?2

? = 16.21 ≈ 16
Hence, option B is correct.
25.1 % of 5902 = ? × 55.96 ÷ 3.82 ×20
= 5902 × | 1 | = ? × 56 ÷ 4 × 20 |
4 |
1476 ÷ 14 ÷ 20 = ?
? = 5.27 ≈ 5
Hence, option D is correct.
53.15% of 426 – 30.45% of 745 = ?2 – 512 – 1600
53% of 426 – 30% of 745 = ?2 – 512 – 40
225.78 – 223.5 + 512 + 40 = ?2
?2 = 226 – 223 + 512 + 40
?2 = 555
?2 = 23.55 ≈ 24
Hence. option C is correct.
1535 √35 + 20% of ? – 124.15 of | 1 | = 6960 |
9 |
1535 35 + 20% of ? – 124.15 of | 1 | = 6960 |
9 |
or, 1535 × 5.916 + ? × | 1 | – 124 × | 1 | = 6960 |
5 | 9 |
or, 9071.85 + | ? | – 13.77 = 6960 |
5 |
Or, ≈ 9072 + | ? | – 14 = 6960 |
5 |
Or, | ? | ≈ 6960 + 14 – 9072 = 6974 – 9072 |
5 |
Or, | ? | = – 2098 |
5 |
Or, ? = – 2098 × 5 = – 10490
Hence, opton B is correct.
162.13 × 9 – (10648) | = 5 |
16 × 14 + 245 + (?)2 |
162.13 × 9 – (10648) | = 5 |
16 × 14 + 245 + (?)2 |
= | 1458 – 22 | = 5 |
224 + 245 + (?)2 |
= | 1436 | = 5 |
469 + (?)2 |
1436 = 5 × (469 + (?)2)
1436 = 2345 + 5 × (?)2
5 × (?)2 = – 909
(?)2 ≈ – 181
(?)2 = 13.452
(?) ≈ 13
(3026.001) + (12.969)2 = ? ÷ | 6 |
23.892 |
(3026.001) + (12.969)2 = ? ÷ | 6 |
23.892 |
Or, ? ≈ (3025) + (13)2 × | 6 |
24 |
Or, ? = (55 + 169) × | 6 |
24 |
⇒ | 224 × 6 | = 56 |

25.12 × 152.94 + 5142 – 6336.83 | = ? |
√360 |
25.12 × 152.94 + 5142 – 6336.83 | = ? |
√360 |
? = | 25.12 × 152.64 + 5142 – 6336.83 |
√361 |
≈ | 25 ×153 + 5142 – 6337 |
√360 |
≈ | 3825 + 5142 – 6337 |

= 138.42 ≈ 139
82.958 × 22.001 – 16.04 × 3.11 | = ? |
(9.002)2 – √145 + (16.997)2 |
82.958 × 22.001 – 16.04 × 3.11 | = ? |
(9.002)2 – √145 + (16.997)2 |
= ? | 82.958 × 22.001 – 16.04 × 3.11 |
(9.002)2 – √145 + (16.997)2 |
or, ? ≈ | 83 × 22 – 16 × 3 | = | 1826 – 48 |
81 – √144 + 289 | 81 – 12 + 289 |
= | 1778 | = | 1778 | = 4.966 ≈ 5 |
370 – 12 | 358 |
Hence, option E is correct.
35.85% of 569.9 + 35.9% of 450.2
≈ 36% × 570 + 36% × 450
? ≈ | 36 | × 570 + | 36 | × 450 |
100 | 100 |
? ≈ 205.2 + 162
? ≈ 367.2
? ≈ 367
Hence, option (B) is correct.
√783.99 × √169.123 + 49.9% of 300 = ? × 9.8
⇒ √784 × √169 + | 50 | × 300 ≈ ? × 10 |
100 |
⇒ 28 × 13 + 150 ≈ ? × 10
⇒ ? ≈ | 514 | = 51.4 |
10 |
⇒ ? ≈ 51
Hence, option (B) is correct.
⇒ 49 + 81 – | 10 | × 555 + 125 ≈ ? |
100 |
(√1224.889 × 16.23) ÷ 4.99 × 4
? ≈ (√1225 × 16) ÷ 5 × 4
? ≈ | 35 × 16 | × 4 |
5 |
? ≈ 112 × 4 = 448
∴ ? ≈ 450
Hence, option (C) is correct.
