Answers and Solutions
(1-5) :
- (3) No. of qualified candidates in the year 2005 = 900 × 64100 = 576
No. of male candidates who qualified in the year 2005 = 576 – 176 = 400
Required ratio = 400 : 176
= 25 : 11
- (4) No. of qualified candidates in the year 2006
= 700 × 140100 × 25100 = 245
- (3) Let the appeared candidates in the year 2002 = 500 and qualified candidates in the year 2002 = 400
No. of qualified female candidate = (4008 3 ) = 150
Required% = (150500 100) % = 30%
- (4) No. of qualified candidates in the year 2004 = 724 14 = 252
Total no. of appeared candidates in the year 2004 = (25242 100)% = 600
- (2) No. of qualified candidates in the year 2003 = 480 × 60 100 = 288
No. of qualified candidates in the year 2001 = 249 × 2 – 288 = 210
Required % = (210700100)% = 30%
- (3) Required % = (600700+400+1200+1200+600+900+900 100 ) %
= (6005900 100 ) % = approx 11%
- (5) In 1994 = 0%
In 1995 = No increase
In 1992 = No increase
In 1997 = 0%
- (2) Total sales of Canon printer in the year 1991, 1992 and 1995
= 600 + 900 + 1100 = 2600
Total sales of Canon printer in all the years
= 600 + 900 + 300 + 600 + 1100 + 1000 + 1100 = 5600
Required % = approx 46 %
- (5) Total sales of HP printer in all the years
= 700 + 400 + 1200 + 1200 + 600 + 900 + 900 = 5900
and total sales of Canon printer in all the year = 5600
Required ratio = 5900 : 5600 = 59:56
- (1) The sale of HP Printer from the Previous year
in 1993 = 200% more
1995 = 50% less
1992 = 42.85% less
1994 = 0%
Required answer is 1993
