Use ANNEXURE B to answer the questions that follow.
1.3.1 Determine the approximate distance from stand 14 to the nearest rolling door
Measure the distance from the beginning of stand 10 to the end of stand 17 and hence, determine, to ONE decimal place, the scale of this plan.
1.3.3 The exhibitor's rate for a 4 mx 4 m stand is R22 942.
Cyril stated that he must pay exactly R25 000 for stand 26.

2.2 ANNEXURE C shows the tax rates for individuals for the 2018/2019 tax year.
John (68 years old) received a taxable income of R2 045 364 for the 2018/2019 tax year. He paid a monthly contribution towards a medical scheme for himself and his wife.
Use the information above and ANNEXURE C to answer the questions that follow,
2.2.1 Calculate John's total medical scheme tax rebate for the year.
2.2.2 Hence, calculate the amount of income tax he had to pay for the 2018/2019 tax year. (8)

Use the information above to answer the questions that follow.
2.3.1 Calculate, in rand, Megan's annual gross salary using the following exchange rates:
1 euro = 15,64 South African rands
1 euro = 7,47 Danish kroner
2.3.2 John stated that Megan's total annual deductions (excluding tax) are more than 52% of her annual gross salary.
Verify, showing ALL calculations, whether this statement is valid.
2.4 TABLE 1 on ANNEXURE D shows the top marginal tax rate for individuals in the G20 countries. This table provides present and past data of the top marginal tax rates. It was updated in January 2019.
Use the information in ANNEXURED to answer the questions that follow.
2.4.1 Name the country that has the biggest range between 2019 and the past top marginal tax rates.
2.4.2 Determine, to THREE decimal places, the probability of randomly selecting one of the G20 countries where the latest tax rates changed from the previous tax rate.
2.4.3 Use the 2019 top marginal tax rate and answer the following questions:
Verify, showing ALL calculations, whether the given interquartile range is CORRECT.

QUESTION 3
3.1 Franco is training to become a pilot. The following shows the approximate cost to get a private pilot's licence:
NOTE: Solo flying means to fly the airplane on your own.
3.1.1 Calculate, in rand per minute, the rate for solo flying. (3)
3.1.2 Calculate the total approximate cost to get a private pilot's licence. (5)
3.2 Two years ago Franco had invested R90 000 at an interest rate of 8,5% per annum compounded yearly. (6)
3.3 Verify, with calculations, whether this total amount with interest is enough to pay for a private pilot's licence. Franco noted that not all the students passed the examinations. TABLE 2 and TABLE 3 show information regarding the same group of students that sat for the examinations. All students that failed, attempted the examinations again.
3.3.1 TABLE 2 below shows information regarding the percentage of students that passed or failed the examinations.
TABLE 2: PASS OR FAIL RATE PER ATTEMPT
1ST ATTEMPT | 2nd ATTEMPT | |
Failure rate | 80% | 70% |
Pass rate | 20% | 30% |
Give a possible reason why the probability of passing increased after the first attempt (2)
