b)   116
c)   108
d)   120

10). 11,    12,   26,   81,   328,   ?
a)   1720
b)   1645
c)   1540
d)   1625
e)   1575

1). B) ? = (180/100) × 25501 + (50/100) × 28999 – 7634.97
= (9/5) × 25500 + (1/2)× 29000 – 7635
= 9 × 5100 + 14500 – 7635 = 60400 – 7635 = 52765 = 52770

2). E) 174.995 × 14.995 ÷ 25 + ? + 86.93 × 3.004 = 495
or, 175 × 15 ÷ 25 + ? + 87 × 3 = 495
or, 105+?+261 = 495
or, ? = 495 – 366 = 129 = 130

3). C)140% of 56 + 56% of 140 - √2026 - ? = 40
or, (56 + 56)% of 140 - √2026 - ? = 40
or, 112% of 140 – 45 - ? = 40
or, ? = 1.12  × 140 – 45 – 40 = 156.80 – 85
or, ? = 157 – 85 = 72 = 70

4).E)  5687.285 + 4872.35 ÷ 12 × 6.989
=5 × (3699.98 - ?)
Or, 5687 + 4872/12 × 7 = 5 × (3700 - ?)
Or, 5687 + 406 × 7 = 18500 – 5 × ?
Or, ? = 18500-5687-2842/5 = 9971/5
=1994.2 = 2000

5).A) 1325 × √17 + 20% of ? – 83.99 × ¾
=5500
Or, 1325 × 4.12 + ? × 1/5 – 84 × ¾ = 5500
Or,5459 + ?/5 – 63 = 5500
Or,  ?/5 = 5500 + 63 – 5459 = 5563 – 5459 =104
? = 104 × 5 = 520

6). C)  The series is
4 + (7) = 11 + (13) = 24 + (20) = 44 + (28) = 72 + (37) = 109
7 + (6) = 13 + (7) = 20 + (8) = 28 + (9) = 37

7). A) The series  is +8,+16,+32,+64,+128,…
ie 13 + 8 = 21, 21 + 16 = 37, 37+32 = 69, 69+64 = 133,133+128 = 261

8). A) The series  is +8,+16,+32,+64,+128,…
ie 17 + 8 = 25,25 -10 = 15, 15 + 12 = 27, 27 – 14 = 13,
? = 13 + 16 =29

9).E) The series is +12,+23,+32,+43,+52,+63…..
ie 11 + 1 = 12, 12 + 8 = 20, 20 + 9 = 29, 29 + 64 = 9333, ……
? = 93 + 25 =118

10).B) The series is ×1 + 1, ×2 + 2, ×3 + 3, ×4 + 4, ×5 + 5, …..
ie 11 × 1 + 1 = 12,12 × 2 + 2 = 26,26 × 3 + 3=81, 81 × 4 + 4 =328, ….
? = 328 × 5 + 5 = 1640 + 5 =1645
