Options- A. March & July
- B. April & July
- C. June & September
- D. July & September Discuss
Correct Answer: July & September
Explanation:
Increase in the price of crude oil in the given month with respect to the corresponding previous months:
In March ? (3980 - 3210) x 100 /3210 ? 24%
In April ? (4800 - 3980) x 100/3980 = 20.6%
In May ? (4940 - 4800)/4800 x 100 ? 3%
In June ? (4970 - 4940)/4970 x 100 = 0.6%
In July ? (5730 - 4970 )x100 /4970 = 15.3%
In August ? (6250 - 5730)x 100/5730 = 9.07%
In September ? (7020 - 6250)x 100/6250 = 12.32%
It is shown that in the months of July and September, increase in the crude oil price was more than 10% but less than 20% over the earlier month.
- 2. Which month had less than one percent increase in crude oil price over the earlier month?

In June ? (4970 - 4940)/4970 x 100 = 0.6%
In August ? (6250 - 5730)x 100/5730 = 9.07%
it is clear that in the month of May only increase in crude oil price has less than 1% i.e., 0.6 % over the earlier month.
- 3. If in April the crude oil price would have been lesser than the given by Rs. 223 per metric tonne then how much would have been the percentage increase in price over the earlier month?
