Bobby lives in India and wants to start his own take-away business - NSC Mathematical Literacy - Question 4 - 2021 - Paper 1

To calculate the total cost of one plate of chicken biryani, we first find the total cost of ingredients for 8 plates:

Total Ingredient Cost = Rs200 (Chicken) + Rs120 (Rice) + Rs12 (Masala) + Rs60 (Other)

Total Ingredient Cost = Rs392

Dividing by 8 for the cost per plate:

Cost per plate = ( \frac{392}{8} = 49 \text{ Rs} )

Now, add the packaging cost of Rs2.43:

Total Cost per plate = Rs49 + Rs2.43 = Rs51.43.

To verify Bobby's claim, we need to calculate the profit:

Selling Price = Rs80

Cost Price = Rs51.43

Profit = 80 - 51.43 = Rs28.57

Profit percentage is calculated as:

Profit Percentage = ( \frac{Profit}{Cost Price} \times 100 = \frac{28.57}{51.43} \times 100 \approx 55.54% )

Since the profit percentage is greater than 50%, Bobby's claim is valid.

From TABLE 5, the exchange rate is:

1 ZAR = 0.206839 Rs

Price of masala powder in Rs = Rs12

To convert to ZAR:

Price in ZAR = ( \frac{12 ext{ Rs}}{0.206839 ext{ Rs/ZAR}} \approx 57.96 ext{ ZAR} )

Using Janet's equation:

Total cost = R600 + 13p

Set it to R1 380:

R1 380 = R600 + 13p

Rearranging gives:

13p = R1 380 - R600 = R780

Now, divide by 13:

p = ( \frac{780}{13} = 60 )

To find the minimum number of plates Janet must sell, we need to find when income exceeds costs. Janet’s fixed cost is R600.

Considering her variable cost of R13 per plate, she needs to sell plates such that:

Income = Cost. This happens when:

( 13p + 600 < 13p )

To find the break-even point, we set:

Income = 13p (selling price) and Cost = R600 + 13p. For her to start making profit, the minimum p must be calculated.

To find the probability, we look at the total number of tourists from 'Other' countries divided by the total tourist arrivals. This would be calculated from the data provided in ANNEXURE C.

By evaluating the data from ANNEXURE C, we can identify the trend. We see whether the number of arrivals increased, decreased, or remained stable over the years.

To verify Bobby’s statement regarding tourist arrivals from Bangladesh, we calculate:

If more than 4,500,000 of 10,93 million arrivals in 2019:

Calculate as follows with the provided data to check the accuracy of Bobby's claim.

The total percentage of tourist arrivals mentioned (99.8%) could be due to rounding errors, or it might indicate that some arrivals were not accounted for, leading to a slight discrepancy from a complete 100%.
