Answer :-

1. 2; The series is +4, +14, +34, +74 ...

2. 5; The series is +8 –1, +16 – 3, +32 – 5, ...

3. 1; The series is +12  + 1, +22  – 1, +32  + 1, +42  – 1, ...

4. 4; The series is ×2 – 1, ×3 + 1, ×4 – 1, ×5 + 1 ...

5. 3; The series is +42  – 3, +82  – 6, +122  – 9, +162  – 12, ...

6. 4; Labelled price = (884 * 100) / 85 = 1040

                 CP =   (884 * 100) / 100.5 = 800

If there is no discount then required per cent

profit =  (800–1040) * 100 / 800 = 30%

7. 3; Let the sum be `X.

   Rate = (768 * 100) / X * 8 = 9600 / X % pa

  SI for first 4 years = (X * 4 * 9600) / 100 * X = 384

  SI for last 4 years =  (4X * 4 * 9600) / 100 * X = 1536

  Total SI = 384 + 1536 = `1920

8. 3;

 1150848 = 555000 * (20 / 100)^t

1296 / 625 =  (6 / 5)^t

(6 / 5)^4 = (6 / 5)^t

t = 4

9. 4; Let the cost price be `X.

Then, X × (15 + 15)% = 96

X = (96 * 100) / 30 = 320

10. 2; 

4X + 3X = 98

X = 14

A’s age = 56

B’s age = 42

ratio of after 14 year A’s age to B’s is 56 + 14 : 42 + 14

   The ratio of A’s age to B’s is 70 : 56 = 5 : 4
