1. d) 2. b) 3. b) 4. d) 5. a) 6. b) 7. d) 8. a) 9. e) 10. d)

Solution:
1). 56   57   48   73   24   105   -10
Here 56 +12 = 57;
57 - 32 = 48; 48+ 52 = 73; 73- 72 = 24;
24 + 92 = 105; 105 -112 = -16

2). 3   1   3   0.7   3   0.6   3
3 × 1/3 = 1;
1 × 3 = 3;
3 × ¼ = 0.75;
0.75 × 4 = 3;
3 × 1/5 = 0.6;
0.6 × 5 = 3;
3 × 1/6 = 0.5;
0.5 × 6 = 3.

3). 2   6   13   26   54   100   197
Here 2 × 2 + 2 = 6; 6 × 2 + 1 = 13;
13 × 2 + 0 = 26; 26 × 2 - 1 = 51;
51 × 2 - 2 = 100; 100 × 2 - 3 = 197

4). 2   2   13   59   363   2519   20161
Here 2 × 3 - 4 = 2; 2 × 4 + 5 = 13;
13 × 5 - 6 = 59; 59 × 6 + 7 = 361;
361 × 7 - 8 = 2519; 2519 × 8 + 9 = 20161

5). 1   8   66   460   2758   13785   55146
Here 1 × 9 - 1 = 8; 8 × 8 + 2 = 66; 66 × 7 - 3 = 459;
459 × 6 + 4 = 2758; 2758 × 5 - 5 = 13785; 13785
× 4 + 6 = 55146

6). Production of Petrol from country O, Q, R and M = 16 + 25 + 15 + 18 = 74 thousand barrels
Consumption of Petrol from country M, N, P and S = 15 + 6 + 3 + 4 = 28 thousand barrels
Required difference = 74 – 28 = 46 thousand barrels = 46000 barrels.

7). Excess Petrol = (production – consumption)
Required average = 3 + 14 + 6 + 3 + 9 + 5 + 6 / 7 = 46 / 7 = 6.5714 thousand barrels = 6571 barrels.

8). Total Consumption of Petrol of country M, N and Q = 15 + 6 + 16 = 37
Total production of Petrol of country M, O, P and S = 18 + 16 + 6 + 10 =50
Required% = 37 / 50 × 100 = 74%

9). Difference between production and consumption of
Country M = 3 thousand barrels
Country N = 14 thousand barrels
Country O = 6 thousand barrels
Country P = 3 thousand barrels
Country Q = 9 thousand barrels
Country R = 5 thousand barrels
Country S = 6 thousand barrels
Therefore Country N has the maximum difference.

10). Excess Petrol from country N and S = 14 + 6 = 20 thousand barrels
Production of Petrol in country Q and R = 15 + 25 = 40 thousand barrels
Required ratio = 20 : 40 = 1 : 2.
