Important for :
1
Out of the number of qualifies candidates from State P in 2008, the ratio of male to female candidates is 11 : 7. If the number of female qualified candidates from State P in 2008 is 126, what is the number of appeared candidates (both male and female) from State P in 2008?
» Explain it
E
Given ratio of qualified male and female from State P in 2008 is 11 : 7.

Let the total number of qualified students = x.

 7x =  126 11 + 7
 ⇒      x    = 126 × 18 =  324. 7

Let the total number of appeared candidates be y.

Then y × 60% = 324

 ∴   y = 324 × 100 = 540. 60

Hence, option E is correct.

2
The number of appeared candidates from State Q increased by 100% from 2006 to 2007. If the total number of qualified candidates from State Q in 2006 and 2007 together is 408, what is the number of appeared candidates from State Q in 2006?
» Explain it
C
Let the number of appeared candidates from State Q in 2006 be x.

Then, the number of appeared candidates in 2007

 =   x + 100 × x 100
=   2x

According to the question,

 x × 30 + 2x × 45 = 408 100 100

 ⇒ 3x + 9x = 408 10 10
⇒   12x = 4080
⇒       x = 340.

Hence, the number of candidates from State Q in 2006 is 340.

Hence, option C is correct.

3
What is the difference between the number of qualified candidates from State P in 2006 and that in 2007?
» Explain it
A

As per the question, we get

60% of 450 – 43% of 600

Required Difference

 = 60 × 450 – 43 × 600 100 100

= 270 – 258 = 12.

Hence, option A is correct.

4
If the average number of qualified candidates from State Q in 2008, 2009 and 2010 is 210, what is the number of qualified candidates from State Q in 2010?
» Explain it
D
Let the percentage of candidates who qualify from State Q in 2010 be x%

Then,

Average

 = 60% of 280 + 50% of 550 + x% of 400 3
=   210

⇒   168 + 275 + 4x = 630
⇒   4x = 630 – 443 = 187
 ⇒   x = 187 = 46.75%. 4

∴   Qualified candidates from State Q in 2010 = 46.75% of 400 = 187.

Hence, option D is correct.

5
If the ratio of the number of qualified candidates from State P in 2009 to that in 2010 is 14 : 9, what is the number of qualified candidates from State P in 2010?
» Explain it
C
The ratio of qualified candidates from State P 2009 to that in 2010 is 14 : 9.

Now, in 2009 the number of qualified candidates
 = 480 × 70 100
= 336

Let the number of qualified candidates from State P in 2009 be 14x and in 2010 be 9x. Then,

⇒ 14x = 336 ⇒ x = 24

In 2010 the number of qualified candidates
=   9 × 24
=   216.

Hence, option C is correct.
