ANSWERS

I.

01. Option A 

Explanation:

Maximum possible runs scored by Arpit in Match-1 = 27

Maximum possible runs scored by Arpit in Match-3 = 19

Maximum possible percentage contribution:

(27+100+19+53)/(270+300+240+200)x100% = 199/1010×100%
= 19.7%

02. Option B

Explanation:

Maximum possible total runs scored by Chatur in the four matches = 27 + 30 + 110 + 20 = 187.

In such a case minimum possible total runs scored by Arpit in the four matches = 23 + 100 + 13 + 53 = 189.

Difference = 189 – 187 = 2 (minimum possible) Subsequently total runs scored by Bimal in the four matches = 88 + 65 + 19 + 52 = 224.

Also, total runs scored by Elan in the four matches = 60 + 30 + 78 + 19 = 187

Absolute difference = 224 – 187 = 37

03.Option C

Explanation:

Individual ranges for total score:

Arpit-> 189-199

Bimal-> 218-224

Chatur-> 182-187

Dinu-> 223

Elan-> 187-188

Least total will be of Chatur (Rank 5)

2nd least will be Elan (Rank 4)

Rank 3 must be of Arpit.

It is not possible to determine the exact ranks of Bimal and Dinu.

II.

04. Option D

Explanation :

If	2	th of physics are female teachers, then
	9

Male teachers = 1 –	2	=	7	th of physics
	9		9

Let's take x% of male physics teacher equal to Chemistry teachers, then

⇒  x% of Chemistry teacher =	7	th of physics
	9

⇒  x% of (23% of 1800) =	7	th of (17% of 1800)
	9

⇒  x% of 23 =	7	th of 17
	9

⇒  x =	7	×	17	× 100 = 57.4% ≈ 57%
	9		23

05. Option A

Explanation :

(Chemistry + English + Biology)% of Total number of teachers

⇒ (23 + 27 + 12)% of 1800

⇒ 62% of 1800

⇒	62	× 1800 = 1116.
	100

06. Option C

Explanation :

Req. difference = [(English + Physics) – (Mathematics + Biology)]% of 1800

⇒ [(27 + 17) – (13 + 12)]% of 1800

⇒ (44 – 25)% of 1800

⇒ 19% of 1800 =	19	× 1800 = 342.
	100

07. Option D

Explanation :

No. of teachers who teaches Mathematics : No. of teachers who teaches Hindi

  13% of 1800 : 8% of 1800

  13 : 8.

08. Option D

Explanation :

Percentage of Mathematics teacher = 13%

After increased by 50% it becomes, 13 + 6.5 = 19.5%

Similarly,

Percentage of Hindi teacher = 8%

After increased by 25% it becomes, 8 – 2 = 6%

Now, percentage of total teachers becomes, 19.5 + 6 = 25.5%

Therefore, 25.5% of 1800

⇒	25.5	× 1800 = 25.5 × 18 = 459.
	100
