Explanations for answers

1. Mechanic and lawyer are both occupations. (Answers)
2. The series is obtained as follows: -2,-3,-4 (i.e., 19-2; 17-3; 14-4 ...). The next number in the series is obtained by subtracting 5 from 10. (Answers)
3. The first pair of numbers is 12, 12. The next pair is 3 less (9,9). The next pair is 3 less again (6,6). The next pair would be 3,3. Therefore, the answer is (4). (Answers)
4. The time needed to produce 1 black and white page is (1 ÷ 6), or 1/6 of a minute. The time needed for 12 black and white pages is 12 × 1/6 or 12 ÷ 6. The time needed for 2 colour pages is 1 minute (given). The total amount of time needed, therefore, is (12 ÷ 6) + 1 minutes. (Answers)
5. Send and receive both refer to delivery (or transmission). (Answers)
6. The series is obtained as follows: ×2, ×3, ×4, ×5 (i.e., 1 × 2; 2 × 3; 6 × 4; 24 × 5...). The next number in the series is 120 × 6 = 720. (Answers)
7. With 5 kg of cement, take the proportions given and multiply by 5:(1 × 5) + (3 × 5) + (5 × 5) = alternative 2. (Answers)

15. Metaphor and translation involve conversion of something into something else. (Answers)
16. The numbers are in pairs 4,8; 9,18; 16,32; 25,? . The second number in each pair is twice the value of the first number. The next number in the series can be found by multiplying 25 × 2 = 50. (Answers)
17. Team and family are groups of people. (Answers)
18. The series is obtained as follows:+3, ×2, +5, ×2 (i.e, 2 + 3; 5 × 2; 10 + 5; 15 × 2 ). The next number in the series is 30 + 7 = 37. (Answers)
19. The series is obtained as follows: - 4, +2, -5, +3, -6 (i.e., 30 - 4; 26 + 2; 28 - 5; 23 + 3; 26 - 6). The second number in the series was obtained by adding 2, the fourth was obtained by adding 3. The sixth number in the series would be obtained by adding 4. 20 + 4 = 24. (Answers)
20. Optimistic and pessimistic describe expectations. They are opposites, and as noted in the instructions, opposites refer to a single concept. (Answers)
21. The work requires 9 × 15 employee - days (e.g., 135 employees for 1 day). With 3 additional employees who are twice as fast as each of the original 9 employees, it is like having 9 + (3 × 2) employees. Therefore, the number of days required is given in choice 4. (Answers)
22. Every second number in the series is a 12. The odd numbers in the series are obtained as follows: the third number is the first plus 5 (13 + 5), the fifth number is the third plus 6 (i.e, 18 + 6). The seventh number would be the fifth number plus 7 (i.e., 24 + 7 = 31). (Answers)
23. For the first 25 manuals, the cost for 1 manual is $ 4/12. The cost for the first 25 manuals equals 4/12 × 25. Since there is a 10% discount after the 25th manual, the cost for 1 of the later manuals is $( 4/12 ) - (4/12) × 10%). Since there are 10 at the reduced price, the quantity in the brackets is multiplied by 10. The cost for all of the manuals can be found by adding the costs for the first 25 manuals and the cost for manuals 26 to 35. (Answers)
24. Meadow and forest are both natural habitats or tracts of land. (Answers)
25. Amusement and diversion are activities which can occupy time (pastimes). (Answers)

31. The series is obtained as follows: (number² -1), +1, (number² -1), + 1 (i.e., 2² -1; 3 + 1; 4² -1; 15 + 1). The next number would be (16² -1) = 255. (Answers)

36. Marcel can type 5 pages in ½ hour, or 5/(½) per hour. Paul can type 5 × 3 pages in 2/3 × ½ hours, or 5 × 3/(1/3) per hour. The number that can be typed in 2 hours by the two people is 2 5/(½) + 5 × 3/(1/3). (Answers)
37. The key part to this question is to realize that the question asks for the total discount, not the sale price. The original price is 100 (percent). The sale price after the two discounts is 100 × (.65 × .90). Therefore, the discount is 100 - 100 × (.65 × .90). (Answers)
