E + E x 50/ 100 =142500
? E + E x 1/2 =142500
? (2E + E)/2 =142500
? 3E =142500 x 2
? E =142500 x 2/ 3
? E = 47500 x 2
? E = Rs. 95000- 5. For which course is the number of boys the minimum?
Options- A. A
- B. C
- C. E
- D. F Discuss
Correct Answer: A
Explanation:
As per first graph,
The number of students for course A = Total number of students x 20%
As per second graph,
The number of girls for course A = Total number of girls x 30%
Number of boys in course 'A' = The number of students for course A - The number of girls for course A
Number of boys in course 'A' = (1200 x 20/100 ) - ( 800 x 30/100 ) = 240 - 240 = 0
Number of boys in course 'C' = (1200 x 5/100 ) - (800 x 2/100) = 60 - 16 = 44
Number of boys in course 'E' = (1200 x 12/100 ) - 800 x 14/100 ) = 144 - 112 = 32
Number of boys in course 'F' = (1200 x 13/100 ) - ( 800 x 14/100 ) = 156 - 112 = 44
Hence, in course 'A' number of boys is minimum which is Zero.- 6. For Company Y, in which year is the percent of increase in percent profit over that of previous year the highest?
