Answers:

Answer.1. 2;
The series as:
(13 + 1) = 2
(23 – 1) = 7
(33 + 1) = 28
(43 – 1) = 63
(53 + 1) = 126
(63 – 1) = 215

Answer.2. 1; 
The series as:
12 × 2 + 3 = 27
27 × 2 + 3 = 57
57 × 2 + 3 = 117
117 × 2 + 3 = 237
237 × 2 + 3 = 477
477 × 2 + 3 = 957.

Answer.3. 2;
The series as:
452 + 1 = 2026
462 + 2 = 2188
472 + 3 = 2212
482 + 4 = 2308
492 + 5 = 2406
502 + 6 = 2506

Answer.4. 4

Answer.5. 3

Answer.6. 4;
Let the total production be x. Then,
0.87x = 204841
=> x = 235450 approximately.

Answer.7. 1;
Total number of products produced in the year = 214704
Total revenue generated = 214704 x 11.37 
= Rs. 2,44,1184.48
