C7 - Quantitative Methods (10-20 Qs) SC Flashcards
A 6% bond is currently priced at £98.15. The bond is one year from maturity and will be redeemed at par
What is the internal rate of return (IRR)?
A) 1.1%
B) 1.9%
C) 6.0%
D) 8.0%
D - 8.0%
£98.15 = £106/(1+r).
Rearranged, R = (£106/£98.15)-1 = 0.07998 so 8%, or use trial and error.
If using T&E, go for one of the middle values and then adjust up and down from there, as will be less calculations
A repayment mortgage of £100,000 is taken out over 25 years
What is the annual repayment required at the end of each year if the rate of interest is fixed at 9%
A) £10,181
B) £11,233
C) £12,120
D) £13,204
A - £10,181
£100,000 = annual cash flow x annuity factor
Annuity factor = 1/0.09(1-(1/(1.09)^25)) = 9.8226
£100,000 = annual cashflow x 9.8226
Annual cash flow = £100,000 / 9.8226 = £10,181
Given the following data, what is the value of the 1st, 2nd and 3rd quartiles?
1 : 3 : 5 : 7 : 9 : 11: 17 : 18 : 20 : 22 : 23 : 26
A) 1, 7, and 17
B) 5, 11, and 20
C) 11, 20, and 26
D) 6, 14, and 21
D - 6, 14, and 21
25% of observations lie below the first quartile, 50% below the second quartile, 75% below the third quartile, and 100% below the forth quartile. BELOW not below or equal to.
With 12 observations, the first quartile will be a midway between the 3rd and 4th observations (5 & 7 = 6), the second quartile will be midway between the 6th and 7th observations (11 & 17 = 14) and the third quartile will be midway between the 9th and 10th observation (20 & 22 = 21)
The table below gives GDP figures for 5 consecutive years:
Year / GDP (£’s billions)

Taking Y1 as the base year, what is the index in Y5?
A) 102.2
B) 112.0
C) 122.4
D) 132.6
C - 122.4
12.0 / 9.8 x 100 = 122.4
What type of index is the Nikkei 225?
A) Weighted geometric
B) Unweighted geometric
C) Weighted arithmetic
D) Unweighted arithmetic
D - Unweighted arithmetic
The Nikkei 255 (stock market index for the Tokyo Stock Exchange) and Dow Jones Industrial Average (aka DJIA is a stock market index of 30 prominent companies listed on stock exchanges in the United State) are examples of unweighted arithmetic
Which of the following would demostrate most usefully the relationship between two variables?
A) Histogram
B) Scatter Diagram
C) Cumulative Frequency Graph
D) None of the above
B - Scatter Diagram
A scatter diagram shows the plot of two variables, giving a visiual representation of the relationship between them. Linear regression can be used to fit a straight line to summarise the relationship between the two variables by statistically minimising the error terms.
Calculate the sample variance of:
12, 34, 29, 54, 98 and 121
A) 1,723.6
B) 1,823.6
C) 1,895.3
D) 1,921.9
B - 1,823.6
Sample variance (s2) is a measure of the degree to which the numbers in a list are spread out. If the numbers in a list are all close to the expected values, the variance will be small. If they are far away, the variance will be large.
Computing sample standard variance:
Step 1: Get the MEAN (sum all and then divide by no of values) - for this question it is 58
Step 2: Take each observation (value) and deduct the MEAN, square and then sum = ((12-58)^2)+((34-58)^2) + … + ((121-58)^2) = 9,118
Step 3: Take solution from Step 2 and divide by the number of oberservations minus 1 to get the variance = 9,118/(6-1) = 1,823.6
Both MEAN and STANDARD DEVIATION can be computed using the calculator’s stats funcation
The FTSE 100 is a:
A) Weighted arithmetic index of stock prices
B) Unweighted arithmetic index of stock prices

What is the annual percentage rate (APR)?
A) 21.0%
B) 23.8%
C) 25.2%
D) 28.3%
D - 28.3%
Effective APR = ((1.021)^12)-1 = 0.2832 SO 28.32%
How does one derive values from a bar chart?
A) Frequency from height of bars
B) Width of bars equals number of sample
C) Height multiplied by the width equals frequency
D) Area of the bar equals sample population
A - Frequency from height of bars
The frequency of a variable is derived from the height of a bar chart.
(YEAR) X / Y
(1) 90 / 180
(2) 130 / 220
(3) 125 / 300
What is the geometric index value for X & Y for year 2, using Year 1 as base 100?
A) 113.86
B) 126.63
C) 132.87
D) 176.54
C - 132.87
Geometric indexes are constructed by multiplying the price relatives of the constituent stocks and raising the value o the power of 1/n, where n = the number of index constituents.
Price relative stock X = 130/90 = 1.4444
Price relative stock Y = 220/180 = 1.2222
Index = (1.4444 x 1.2222)^(1/2) x 100 = 132.8663 SO 132.87
If interest rates are fixed at 12% per annum, how much would you pay for an annuity (a financial contract between an annuity purchaser and an insurance company) of £8,000 payable at the end of each of the following five years?
A) £24,847.71
B) £27,973.32
C) £24,000.00
D) £28,838.21
D - £28,838.21
Present Value = £8,000 x annuity factor
Annuity factor = 1/0.12(1-(1/(1.12)^5)) = 3.6048
Present Value = £8,000 x 3.6048 = £28,838.21
What type of data are pie-charts most suitable for?
A) Categorical/discrete
B) Continuous
C) Time-series
D) Semi-long
A - Categorical/discrete
Pie charts give a visual representation for discrete data. Pie charts show the relative frequency of categories in the data set by dividing a circle into sections that are proportionate to the relative frequencies of each category. Pie charts are useful to gain a visual representation of how much the total data set that each category represents.
An investor buys 250 shares at £4 each. After 12 months a dividend of 30 pence per share is received, followed by a dividend of 50 pence per share at the end of the second year. The shares are then sold for £3.925 each at the end of year 2.
What is the internal rate of return on this investment
A) 10.02%
B) 9.73%
C) 8.52%
D) 9.00%
D - 9.00%
250 x £4 = £1,000 / 250 x £3.926 = £981.25
250 x £0.30 = £75 / 250 x £0.50 = £125
The only way of doing this is by trial and error: £1,000 = £75/(1+R) + ((£981.25 + £125)/(1+R)^2 = £999.92.
By trying each one, you will find 9% will get you closest to the purchase amount of £1,000.
IRR, or internal rate of return, is a metric used in financial analysis to estimate the profitability of potential investments. IRR is a discount rate that makes the net present value (NPV) of all cash flows equal to zero in a discounted cash flow analysis.
If small market capitalisation stocks outperform all other stocks, the difference between returns on the FTSE All Share Index and the returns on the FTSE-100 index will be:
A) Zero
B) Negative
C) Positive
D) Indeterminate
C - Positive
The FTSE All-Share is a broad market indicator capturing > 50% of the LSE listed firms and adroun 98% by market capitalisation. The FTSE 100 only represents the 100 biggest stocks (in terms of market capitalisation) on the LSE. If small cap stocks out perform large cap stocks, we would expect the FTSE All-Share to out perform the FTSE 100 Index (in this case FTSE All-Share - FTSE 100 performance woud be positive).

Nine shares have the following percentage price change over the last two years =: 22%, 91%, -10%, 14%, 29%, 35%, 45%, 12%, and 82%
What was the median price change?
A) 33.6%
B) 22.1%
C) 35.0%
D) 29.0%
D - 29%
Median is the middle observation when they all the put into numerical order. SO
-10%, 12%, 14%, 22%, 29%, 35%, 45%, 82% and 91%
There are 9 observations, so the 5th observation (29%) is the Median
