In April, crude oil price = Rs. 4800 per metric tonne.
So, reduced crude oil price = 4800 - 223 = Rs. 4577
Hence, required percentage = 4577 - 3980/3980 x 100 = 15%
Increase in the price of crude oil in the given month with respect to the corresponding previous months:
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 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.
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.
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% > 10%
In April ? (4800 - 3980) x 100/3980 = 20.6% > 10%
In May ? (4940 - 4800)/4800 x 100 ? 3% < 10%
In June ? (4970 - 4940)/4970 x 100 = 0.6% < 10%
In July ? (5730 - 4970 )x100 /4970 = 15.3% > 10%
In August ? (6250 - 5730)x 100/5730 = 9.07% < 10%
In September ? (7020 - 6250)x 100/6250 = 12.32 > 10%
Hence, in March, April, July and September i.e.. 4 months the increase in the price of crude oil was more than 10% with respect to the corresponding precious months.
Number o girls enrolled in Dancing in Institute A = 150
Total number of girls enrolled in all the Hobby classes in Institute A = 250 + 325 + 150 = 725 Hence, required percentage = 150/725 x 100 = 20.69
Number of girls enrolled in Stitching in Institute B = 250
Total number of girls enrolled in Stitching in all the Institutions
= 325 + 250 + 50 + 250 + 325 = 1200
Hence, required percentage = 250/1200 x 100 = 20.83 ? 21%
Required percentage = 7020 - 3210 x 100 = 118.69%
As per given above graph , we have
The distance traveled by Truck A = 475
The distance traveled by Truck Truck D = 425
Required ratio = The distance traveled by Truck A : The distance traveled by Truck D
Required ratio = 475 : 425 = 19 : 17
