The simple interest for one year is:The same 10,000 borrowed at 15% simple interest gives interest over two years of:The amount to be repaid after two years on that loan is:Heena borrows 20,000 at 8% compounded annually. The interest for the first year is:At the end of Heena's first year, the principal for the second year becomes:Interest for Heena's second year, worked on the new principal, is:The amount Heena pays at the end of two years is:Heena's total compound interest over the two years is:Simple interest on 20,000 at 8% for two years would have been:Compared with simple interest, compound interest costs Heena an extra:Starting with 100 rupees at 10% for three years, the simple interest earned is:Starting with the same 100 at 10% for three years, the compound interest earned is:Under simple interest the principal:The compound amount after n years is found from the formula using the bracket:Once the amount is known, compound interest is found as:Compound interest on 12600 for two years at 10% per annum works out to:The time period after which interest forms a new principal is called the:When interest is compounded half yearly, the number of conversion periods in a year is:For half yearly compounding, the rate used in each period is:If interest is compounded quarterly, the quarterly rate is:On 12000 at 10% per annum compounded half yearly, the interest for the first six months is:A city of 20,000 people growing at 5% a year from 1997 reaches, by the end of 2000, about:The two most widely used measures of the centre of a data set are the median and the:Adding fifty weights and dividing by fifty gives the:The number that separates ordered data into two equal halves is the:The most frequent value in a data set is the:A data set can have more than one mode as long as those values share the:Numbers that separate data into quarters are called:About what share of the data falls on or below the first quartile?To find the quartiles, you must first find the:The spread of the middle half of the data is measured by the:If the first quartile is 20 and the third is 44, the interquartile range is:An observation that does not fit with the rest of the data is called an:A histogram where a vertical line splits it into mirror halves shows a distribution that is:A histogram whose right-hand side looks chopped off compared with the left is described as:A histogram whose long tail stretches out to the higher values is:A quick graph that shows the exact values while revealing the pattern is a:The variation of data values around the centre is captured by the:A data set whose values sit closely near the mean will have a standard deviation that is:For the data 4, 5, 6, 6, 6, 7, 7, 7, 7, 8, the most frequent value is:For that same set of ten values, the median is the average of which two ordered values?The median of that set, 4, 5, 6, 6, 6, 7, 7, 7, 7, 8, is:Quartiles and percentiles are together described as the common measures of:The median differs from the mean in that the median does not have to be:
