Following graph shows the percentage of students who studied in private schools during 10th class
- In 2007 total number of candidates from different parts of the country was 1000, then how many non- private school students from TN passed the 10th board?
a) 125
b) 275
c) 250
d) 225
e) None of theseAnswer – d) 225
Explanation :
1000*(25/100)*(90/100) = 225 - In 2007 total number of students from private school from HP was 200, then many non-private school students are from Assam
a) 920
b) 940
c) 960
d) 980
e) None of theseAnswer – c) 960
Explanation :
Let total students from all region are P,
(10/100)*P*(25/100) = 200, we got P = 8000
Non- private students from Assam = 8000*(16/100)*(75/100) = 960 - If total passed students from J& K was 220, what is the ratio between the numbers of private students in TN to the number of non-private school students from Rajasthan?
a) 25: 302
b) 25:304
c) 25:308
d) 23:304
e) None of theseAnswer – b) 25:304
Explanation :
(11/100)*P = 220, P = 2000
Now ratio = 2000*(25/100)*(10/100) : 2000*(38/100)*(80/100) = 25 : 304 - If the number of private school students in Assam was 100, then how many candidates passed the examination from all parts from the country?
a) 2000
b) 2500
c) 3000
d) 4000
e) None of theseAnswer – b) 2500
Explanation :
(16/100)*P*(25/100) = 100, P = 2500 - If there is a increase of 10% and 20% students in Rajasthan and HP in the year 2008 respectively and the number of candidates passed from J&K in 2007 was 110, what would be the approximate number of students passed from Rajasthan and HP in the year 2008?
a) 438
b) 498
c) 538
d) 548
e) None of theseAnswer – c) 538
Explanation :
Let total number of students be P,
(11/100)*P = 110, P =1000
In 2007, Rajasthan = 1000*(38/100) = 380 and HP = 1000*(10/100) = 100
In 2008, Rajasthan = 380*(110/100) = 418 and HP = 100*(120/100) = 120
Total = 418 + 120 = 538
