Solution:

1). E)? x 4.80 = 5836 – (2465 ÷ 49.3)% of 6872 = 5836 – 50% of 6872
= 5836 –(1/2) x 6872 = 5836 – 3456 = 2400
? = 2400/4.80 = 500

2). B)?% of 560 = 500 – (100% of 260 + 25% of 260) = 500 – (260 + 65) = 500 – 325 = 175
or, ? x 5.60 = 175
? = 17500/560 = 1750/56 = 125/4 = 31.25

3). B)? x 4.5 = 7292 – (400% of 650 + 30% of 650) + (20% of 2220)
= 7292 – (2600 + 195) + 444
= 7736 – 2795 = 4941
? = 4941/4.5 = 49410/45 = 5490/5 = 1098

4). C)(?)2 = 1.4 x 625 + 4.2 ÷ 0.7 + 325 x 9.8 + 159 = 875 + 6 + 3185 + 159 = 4225 ? =√4225 = 65

5). A)? × 1.60 = (1/2) x 274 – 45 x1.8 , 
= 137 – 81 = 56
? = 56/1.6 = 35

6). E)The series is x0.5 + 1, ×1 – 1, ×1.5 + 1, ×2 – 1, ×2.5 + 1, …..
Ie 14 × 0.5 + 1 = 8, 8 × 1 – 1 = 7, 7 × 1.5 + 1 = 11.5, 11.5 × 2 – 1 = 22, 22 × 2.5 + 1 = 56,

7). C)The series is


8). D)The series is x1 + 1, x2 + 2, ×3 + 3, x4 + 4, x5 + 5, …
ie 13 x 1 + 1 = 14, 14 x 2 + = 30, 30 x 3 + 3 = 93, 93 x 4 + 4 = 376, 376 x 5 + 5 = 1885,

9). A)  The pattern is -2, +4 (Alternate) The series is a combination of two series


10). B)The series is +12 + 1, +22 + 1, +42 + 1, +82+ 1, +162 + 1, …

 ie 9 + 12 + 1 = 11, 11 + 22+ 1 16, 16 + 42 + 1 = 33, 33 + 82+ 1 = 98, 98 + 162+ 1 = 355,
