Question

Directions: The line graph shows the monthly average Sensex report from May'14 to November'14.

In which month did the average Sensex reading show a greater decrease during the given period?

• A. June
• B. July
• C. August
• D. October
• E. November

Hint:

Work out the point-to-point change for every consecutive pair of months and pick the one with the largest fall.

Answer 1

Answer: (E)

The readings from the graph are: May = 10337.68, June = 10631.12, July = 10120.01, August = 9734.22, September = 9964.29, October = 10536.16, November = 9839.69.

Work out the change from each month to the next:
May to June: 10631.12 - 10337.68 = +293.44 (rise)
June to July: 10120.01 - 10631.12 = -511.11 (fall)
July to August: 9734.22 - 10120.01 = -385.79 (fall)
August to September: 9964.29 - 9734.22 = +230.07 (rise)
September to October: 10536.16 - 9964.29 = +571.87 (rise)
October to November: 9839.69 - 10536.16 = -696.47 (fall)

Comparing the three falls (511.11, 385.79 and 696.47 points), the biggest drop by far is the 696.47-point fall going into November.

So the month with the greater decrease is November, option (e).
