1、income/expense data of a single house hold附注： profit can be negative答案：dprofit equals income MINUS expenses . in this question wedont have to calculate the exact profit，It is enough to examine the distance between theanswer(a): in 1993 the distance between the lines is of 6 squares。there is a profit(since the dark greenline is above the light grenline)of 6 squares。answer(b): in 1996 the distance between the lines is of 7 squares。there is a damage(since the light grenline is above the dark greenline)of 7 squares。answer(c): in 1997 the distance between the lines is of 6 squares。there is a damage(since the light grenline is above the dark greenline)of 6 squares。answer(d): in 1999 the distance between the lines is of 10 squares。there is a profit(since the dark greenline is above the light grenline)of 10 squares。in concexclusion the largest profit(consiring the options given in the answers)was in 1999 .2、income/expense data of a single house hold附注： profit can be negative答案：bwere looking for two dots that overlap(that is one dot that represents both the income and the expenses)。there is only one : in 1998。note : we are not looking for a cutting point between the lines，Since the lines themselves have no meaning。the figures were examined once a year and not continuously and so we cant know what were the income and ex Penses during 1994。for this reason answer(c)is incorrect and so is answer(d)。3、daily average number of swimmers-alde burgh beach答案：bin this question one should make an estimation by looking at the numbers(there is no need to calculate)and see that 2004 appears to be the largehere is the long calculation the number of swimmers each year :2003: 30 20 80=1302004: 40 80 6070 50 40=1602006: 30 60 30=1203、daily average number of swimmers-alde burgh beach答案：din this question we need to find the year in which one of the groups equals of all three .we can use the data we calculated on question 13 3360 in 2006 there were 120 swimmers altogether，and 60 of them(which is half of 120)were menote : to answer this question one can make an estimation by looking at the numbers。if one group equals the sum of the other groups，Then the sum of the two remaining groups also equals the sum。we need to find a year in which one of the columns equals the other two .5、daily average number of swimmers-alde burgh beach答案：canswer(a): the number of men swimmers(dotted column)in 04 is 80，in 05 its 50 and in 06 its 60。thus，the number of men swimmers dropped between 04 and 05 and this answer is incorrect .answer(b): the number of women swimmers(dark column)in 03 is 30，in 04 its 40 and in 05 its 70。thus，The number of women swimmers grew between 03 and 05 and this answer is incorrect(you can also see The dark columns in The diagram rising)answer(c): the number of children swimmers(striped column)in 03 is 80，in 04 its 60，in 05 its 40 and in 06 its 30。thus，The number of children swimmers decreated between 03 and 06 and this answer is correct(you can also see The striped columns in The diagrect)answer(d): the number of men swimmers(dotted column)in 03 is 20，in 04 its 80 and in 05 its 50。thus，the number of men swimmers dropped between 04 and 05 and this answer is incorrect .6、daily average number of swimmers-alde burgh beach答案：danswer(a): the number of children in 03 is 80 and in 04 is 60，which is 20 children less。20 makes 25% of the 80 children in 03，(which make the whole)。answer(b): the number of children in 04 is 60 and in 05 is 40，which is 20 children less。20 makes 33.33% of the 60 children in 04，(which make the whole)。answer(c): the number of children in 05 is 40 and in 06 is 30，which is 10 children less。10 makes 25% of the 40 children in 05，(which make the whole)。thus the statements in answers(a)and(c)are both correct and the correct answers is(d)。7、the following diagram contains data regarding the bus traffic and number of passanger s On each bus，On a certain day at the central station in londuseach bus arrives at the station，waits a while and leaves again to its destination。each line in the diagram represents a certain bus。the left dot States the time of arrival to the station and the right dot States the time of de partur E from the station .the height of the line States the number of passanger who got off at the station .For example，at 12: a bus with 55 passengers arrives at the station，waits an hour and leaves again。答案：aThe correct answer is (A)。the waiting time at the station is the time that passes between the arrival of the bus to the station(the left dot)And the time of its departuremeaning，the waiting times are discribbed in the chart by the highlighted horizontal lines。were looking for the shortest waiting time(in other words，the shortest line)。the shortest horizontal line is half an hour(the bus that arrived at the station at 83360 and left at 933600)。8个，the following diagram contains data regarding the bus traffic and number of passanger s On each
