Correct Answer: 3 : 4
Explanation:
Given:-Total number of students for course D = 35% of 1200 = 420
Number of girl students for course D = 30% of 800 = 240 ,
Number of boy students for course D = Total number of students for course D - Number of girl students for course D = 420 ? 240 = 180
Required ratio = Number of boy students for course D : Number of girl students for course D
Required ratio = 180 : 240 = 3 : 4
Correct Answer: 16
Explanation:
Correct Answer: 250
Explanation:
Correct Answer: 720
Explanation:
Correct Answer: 5000 tonnes
Explanation:
Differnce between the production of foodgrains during 2004 and 2008 = 35 - 30 =5 thousand tonnes.
Correct Answer: 100%
Explanation:
Percentage increase in food grain production = (30 - 15 )/15 x 100 = 100%
Correct Answer: 2004
Explanation:
Total production in 2005 and 2007 = 20 + 15 = 35 thousand tonnes. This total production is equal to the production in the year 2004.
Correct Answer: 2003 and 2004
Explanation:
Rate of change in the amount of production in the year 2004 over the year 2003 = (Production in 2004 - Production in 2003 ) x 100/ Production in 2003
Rate of change in the amount of production in the year 2004 over the year 2003 = (35 - 30) x 100 / 30 = 5 x 100 / 30 = 16.67%
Similarly
Rate of change in the amount of production in the year 2006 over the year 2005 = (25 - 20) x 100 / 20 = 5 x 100/20 = 25%
Rate of change in the amount of production in the year 2007 over the year 2008 = (30 - 15) x 100 / 15 = 15 x 100/15= 100%
Rate of change in the amount of production in the year 2006 over the year 2007 = (25 - 15) x 100 / 15 = 10 x 100/15= 66.67%
Hence, it is clear that the rate of change in the amount of production during the consecutive years 2007 and 2008 is at the highest level.
Correct Answer: 0.4
Explanation:
Mean of annual increase in sale from 2003 to 2008 = (Sale in 2008 - sale in 2003 )/ (Difference in years)
Mean of annual increase in sale from 2003 to 2008 = 10.5 - 8.5/ 5 = 0.4
