Directions:(1-10) What approximate value will come in place of question mark (?) in the following questions? (You are not expected to calculate the exact value.)
1. Question
27.05 x 24.96 + 38.94 x 64.01 + 21.97 x 30.06 = ? x 25.98 + 9.04
? x 26 ≈ 27 x 25 + 39 x 64 + 22 x 30 – 9
? x 26 = 675 + 2496 + 660 – 9
? x 26 = 3822
? = 3822/26 = 147
2. Question
? ≈ (90/3) – 7 x 15 + ∛125
= 30 – 105 + 5
=-70
3. Question
40% of 2648 + 35% of 1823 = 50% of ?
0.5 x ? ≈ 0.4 x 2650 + 0.35 x 1820
= 1060 + 637 = 1697
=> ? = 3394 ≈ 3400
4. Question
458 x 15 – 651 x 17 + 519 x 13 = ?
? = 460×15 – 650×17 + 520×13
= 6900 – 11050 + 6760
= 2610 ≈ 2550
5. Question
5163.3453 – 4018.9025 + 3209.2355 – 3146.8554 + 1873.3463 – 718.534 = ?
? ≈ 5160 – 4020 + 3210 – 3150 + 1870 – 720
= (5160+3210+1870) – (4020+3150+720) = 10240 – 7890 = 2350 ≈ 2360
6. Question
4830 ÷ 34 x 13 – 61.13 x 26.89 = ?
? ≈ 142 x 13 – 61 x 27
= 1846 – 1647 = 199 ≈ 200
7. Question
√1199 + √1299 + √1399 + √1499 + √1599 = ?
? ≈ √1200 + √1300 + √1400 + √1500 + √1600
= 34.64 + 36.05 + 37.42 + 38.73 + 40
= 186.84 ≈ 185
8. Question
36 x 47 + 43 x 52 – 77 x 23 = ? x (6)3
? x 216 = 1692 + 2236 – 1771 = 2157
=> ? ≈ 10
9. Question
√1156.1 + √2601.11 – √3363.91 = ?
342 = 1156, 512 = 2601, 582 = 3364
? ≈ √1156 + √2601 – √3364
= 34 + 51 – 58 = 27
10. Question
∛6858.44 – ∛25.81 – ∛10648.79 = ?
193 = 6859, 33 = 27, 223 = 10648
? ≈ ∛6859 – ∛27 – ∛10648
= 19 – 3 – 22 = -6
