ANSWERS
Solutions (1-5)

1.
(2) First number series
4 x 5 + 5 = 25
25 x 4 + 4 = 104
104 x 3 + 3 = 315
315 x 2 + 2 = 632
Therefore: 7 x 5 + 5 = 40 (a)
40 x 4 + 4 = 164 (b)
164 x 3 + 3 = 495 (c)

2.
(4) First number series
7 x 2 + 1 = 15
15 x 2 + 1 = 31
31 x 2 + 1 = 63
Therefore:
11 x 2 + 1 = 23 (a)
23 x 2 + 1 = 47 (b)
47 x 2 + 1 = 95 (c)
95 x 2 + 1 = 191 (d)
191 x 2 + 1 = 383 (e)

3.
(1) First number series
9 x 0.5 + 0.5 = 4.5 + 0.5 = 5
5 x 1 + 1 = 5 + 1 = 6
6 x 1.5 + 1.5 = 9 +1.5 = 10.5
Therefore:
17 x 0.5 + 0.5 = 8.5 + 0.5 = 9 (a)
9 x 1 + 1 = 9 + 1 = 10 (b)
10 x 1.5 + 1.5 = 15 +1.5 = 16.5 (c)
16.5 x 2 + 2 = 33 + 2 = 35 (d)

4.
(3) First number series
3 x 1 + 12 = 3 + 1 = 4
4 x 2 + 22 = 8 + 4 = 12
12 x 3 + 32 = 36 + 9 = 45
Therefore,
5 x 1 + 12 = 5 + 1 = 6 (a)
6x 2 + 22 = 12 + 4 = 16 (b)
16 x 3 + 32 = 48 + 9 = 57 (c)
5.
(5) First number series
5 x  6  - 6 = 30 – 6 = 24
24 x 5  - 5 = 120 – 5 = 115
115 x 4  - 4 = 460 – 4 = 456
Therefore,
4 x 6  - 6 = 24 – 6 = 18 (a)
18 x 5  - 5 = 90 – 5 = 85 (b)

Solutions (6 – 10)

6. (3);
In 2000,  Profit of A = 30%
Profit of B = 24%
For A, Profit = (Expenditure * Profit%)/100
= (20*30)/100 = 6 lakhs
Income = 20 + 6 = 26 lakhs
For B, Profit = (15*24)/100 = 3.6 lakhs
Income = 15 + 3.6 = 18.6 lakhs
Total = 26 + 18.6 = 44.6 lakhs

7. (4);
In 2004, Percentage profit of A = 16%
Percentage profit of B = 24%
% = (15*24)/100  = 150%

8. (4);
In 2003, Percentage profit of A = 25%
Expenditure of A = 36 lakh
Profit of A = (25*36)/100 = 9
In 2003, Percentage profit of B = 15%
Expenditure of B = 40 lakhs
Profit of B = (40*15)/100 = 6
Average = (9+6)/2 = 7.5 lakhs

9. (4);
In 2001, Percentage profit of A = 25%
Income of A = 30 lakhs
Expenditure of A = (30*100)/125 = 24lakhs
In 2001, Percentage profit of B = 20%
Income of B = 30 lakhs
Expenditure of B =  (30*100)/120 = 25 lakhs
Total Expenditure  = 49 lakhs

10. (5);
By given data we cannot find the expenditure of B in 2002.
