From above given data ,
Since , The cost of production of both items together by company E is equal to the total cost of production of both items together by C and F of the two companies.
Required answer will be C and F .
Number of Candidates qualified from States A and C together
= 49/100 x 15/100 x 300000 + 61/100 x 18/100 x 300000
= 22050 + 32940 = 54990
Required percentage = 54990/300000 x 100 = 18.33%
Qualified Male Candidates from different states
A ? 4/9 x 49/100 x 15/100 x 300000 = 9800
B ? 6/10 x 61/100 x 18/100 x 300000 = 19764
C ? 3/5 x 45/100 x 23/100 x 300000 = 18630
E ? x 7/13 x 65/100 x 12/100 x 300000 = 12600
F ? 11/19 x 57/100 x 19/100 x 300000 = 18810
G ? 9/20 x 48/100 x 7/100 x 300000 = 4536
Hence, State C and G have equal number of qualified male candidates
Given :- Number of students in college A in the years 2004, 2006 and 2007 = 160 × 103
Also, number of students in college B in the years 2003, 2004 and 2008 = 175 × 103
Required ratio = Number of students in college A in the years 2004, 2006 and 2007 : number of students in college B in the years 2003, 2004 and 2008
= 160 : 175 = 32 : 35
