Explanation With Answers Key:

1). C)(36.01)3 x (4096)1/2× 37.992 ÷ (93x 75.982) = 4?
Or, 4? = [ 363 x √4096 x 382] / 93 × 762
or, (43 x 93 x 43 x 38 x 38) / (93 x 76 × 76)  
= (43×43) / (2×2)
Or, 4? = 43 × 42 = 45
? = 5

2). D)(4809.01 + 9615.96 + 14425.03) ÷ 4.98 + 6.02 = (?)2
Or, (?)2 = [(4809 + 9616 + 14425) / 5] +6
= (28850/5) + 6 = 5770 + 6
Or, ?2 = 5776
? = √5776 = 76

3). B)(35% of 74000) ÷ ? = (123% of 13.02)2 x 2.01
Or, (35×74000)/ 100 ÷ ? =  [(123×13) / 100]2x 2
or, 25900 / ? = (15.99)2 × 2
or, (25900/?) = 16×16×2
?= 25900 / (16×16×2) = 50.58 = 50

4). A)  4/15 of 393 + 7/12 of 473
= ? x (1.99 + 1.01)
or, ? x 3 = (4/15) x 393 + (7/12) x 480
or, ? x 3 = (4/15) x390 + (7/12) x 480
or, ? x 3 = 104 + 280
or, ? = 384/3 = 128 = 127

5). C)
√2809.001 ÷ 7.98 x (12.01)2+ 46.002 = ?
or, ? = √2809 ÷ 8 x (12)2 + 46
or, ? = (53/8) x (12)2 + 46
or, ? = 954 + 46
? = 1000

6). C)18% of 256 + 35% of 290 – 15% of 385=?
Or, ? = 18/100 × 260 + 35/100 × 300 – 15/100 × 400
= 46.8 + 105 – 60 = 151.8 – 60 = 91.8 = 90

7). D)√4090 = 4096 = 64
3√12163 =3√12167 = 23
?2= √4090 ×3√12163 + 49
= 64 × 23 + 49
= 1472 + 49 = 1521 = (39)2
?=39

8). A) 8 4/7 + 9 3/4 – 3 5/8 – ? = 6 29/56
Or, ? = (8+9-3-6) + (4/7 + 3/4 – 5/8 – 29/56)
= 8 + [(32 + 42 – 35 – 29) / 56] = 8 + 10/56 = 8

9). C) 9/42 ÷ 108/63 × 328 – 5/7 + 7/5 = ?
Or, ? = 9/42 × 63/108 × 328 – 5/7 + 7/5
= 41+ 5/7 – 7/5 = 40

10). D) [(16 2/3) × (45/39)] / [(3 15/26) – (3 4/13)] =?
or, ? = (50/3 × 45/39) / (93/26 – 43/13) = (250/13) / [(93-86) / 26]

= 250/13 × 26/7 = 500/7 = 71
