1.What is the total number of questions answered incorrectly by Vishwa?
a. 30
b. 25
c. 36
d. 42
e. 12

C. 36

Number of unattempted questions in History = 35 – 17 =18
Number of correct answers in History = 17 – 6 = 11
Vishwa’s score in History= 11*1 – 6*1/3- 18*1/6= 6.
Hence, Vishwa’s score in Statistics=12.
Let x be the number of questions answered correctly in Statistics, y be the number of questions answered incorrectly and z be the number of unattempted questions
x + y + z = 30
x –y/3-z/6 = 12
So, by trial and error using the two equations the only possibility in the number of attempts in Statistics is 18 out of which 15 are correct and 3 are wrong and 12 unattempted.

Number of questions answered incorrectly by Vishwa in Mathematics = 6.
Let a be the number of questions answered correctly in mathematics, b be the number of questions answered incorrectly and c be the number of unattempted questions
a + b + c = 40
a – b/3 – c/6 = 11
Hence, by trial and error the number of attempts is 22 out of which 16 are correct and 18 unattempted which comes to 11.

So, Attempts in Physics = 125 – (29+17+22+18) = 39.
So, wrong answers in Physics = 9.
So, score in English = 67 – (26+11+6+12) = 12.
Let p be the number of questions answered correctly in mathematics, q be the number of questions answered incorrectly and r be the number of unattempted questions
p + q = 29
p –q/3 – r/6 = 12, here r = 6

So, p – q/3 = 13
p = 17 and q = 12
Hence, correct answers in English = 17, wrong = 12 and unattempted = 6 which comes to 17 – 4 -1 = 12.

Directions:(6-10) Study the graph carefully and answer the questions.
The following bar graph shows the population of eight different states of India. (All figures are in lakhs)

6.If 40% of the female population in Maharashtra and 40% of the female population in Rajasthan are literate, what is the ratio of illiterate male population in Maharashtra to that of illiterate male population in Rajasthan?
a. 29:23
b. 23:29
c. 27:25
d. 25:27
e. None of these

B. 23:29

For Maharashtra:
Number of females = 29 – 15 = 14 lakhs
=>Number of literate females = 0.4 × 14 = 5.6 lakhs
=>Number of literate males = 16 – 5.6 = 10.4 lakhs
=>Number of illiterate males = 15 – 10.4 = 4.6 lakhs
For Rajasthan:
Number of females = 34 – 17 = 17 lakhs
=>Number of literate females = 0.4 × 17 = 6.8 lakhs
=>Number of literate males = 18 – 6.8 = 11.2 lakhs
=>Number of illiterate males = 17 – 11.2 = 5.8 lakhs
Corresponding figure for Rajasthan for illiterate males is 5.8 lakhs
=> Required ratio = 4.6:5.8 = 23:29

7.Which state has the second highest ratio of male population to total population?
b. Karnataka
c. Maharashtra
e. Gujarat

The ratio of number of males to total population for all states is:
Maharashtra: 15/29 = 0.51
Gujarat: 16/28 = 0.57
Rajasthan: 17/34 = 0.5
Karnataka: 16/31 = 0.51
Therefore, the ratio is second highest for Uttar Pradesh.

8.Kerala state (not included in the bar graph) has a female literacy rate of 80%. The male population of Kerala is 80% of the average male population of the given eight states and the total literate population of Kerala is 80% of the average literate population of the given states. If there are 6.5lakhs literarte females in kerala, what is the total population of kerela?

A. 21.625 lakhs
B. 20.125lakhs
C. 21.225lakhs
D. 22.375lakhs
E. 22.585lakhs

C. 21.225lakhs

Average male population = (15 + 16 + 19 + 14 + 18 + 16 + 17 + 16)/8 = 16.375 lakhs
=>Male population of Kerala = 0.8 × 16.375 = 13.1 lakhs
Average literate population = (16 +18 + 20 + 16 + 19 + 17 + 18 + 17)/8 = 17.625 lakhs
=>Literate population of Kerala = 0.8 × 17.625 = 14.1 lakhs
Number of literate females in Kerala = 6.5 lakhs
Since female literacy rate in Kerala = 80%
Total female population of Kerala = 6.5 / 0.8 = 8.125 lakhs
Total population of Kerala = 8.125 + 13.1 = 21.225 lakhs

9.Which of the following statements is false?

a. If the male literacy rate in Tamilnadu is 60%, the female literacy rate is 45.56%.
b. If the male literacy rate in Karnataka is 70%, the female literacy rate is 36.25%.
c. The ratio of literate population to total population of Uttar Pradesh is more than that of Madhya Pradesh.
d. The ratio of literate population to total population of Andhra Pradesh is more than that of Gujarat.
e. None of these

D. The ratio of literate population to total population of Andhra Pradesh is more than that of Gujarat.

(a) Male population = 18 lakhs
Literate Male population = 18*0.6 = 10.8 lakhs
Female population = 36-18 = 18 lakhs
Literate female population = 19-10.8 = 8.2 lakhs
Female literacy rate = 100*8.2/18 = 45.56%
Thus, the statement is true.
(b) 32 total 16 male 17 literate
Male population = 16 lakhs
Literate Male population = 16*0.7 = 11.2 lakhs
Female population = 32-16 = 16 lakhs
Literate female population = 17-11.2 = 5.8 lakhs
Female literacy rate = 100*5.8/16 = 36.25 %
Thus, the statement is true.
(c)
Required ratio for Uttar Pradesh = 20:35 = 0.57
The ratio is greater for Uttar Pradesh.
Thus, the statement is true.
(d)
Required ratio for Andhra Pradesh = 17:33 = 0.51
Required ratio for Gujarat = 18:28 = 0.64
The ratio is greater for Gujarat.
Thus, the statement is true.

10.If the female literacy rate in each state is 50% what is the average number of literate males in a state?
a. 981050
b. 981150
c. 981250
d. 991450
e. 991250

C. 981250

 State Total Population Male Population Literate Population Literate Female population=(Total population – Male Population)*0.5 Literate Male population=(Literate Population – Literate Female Population) Maharashtra 29 15 16 7 9 Gujarat 28 16 18 6 12 Uttar Pradesh 35 19 20 8 12 Madhya Pradesh 29 14 16 7.5 8.5 Tamil Nadu 36 18 19 9 10 Andhra Pradesh 33 16 17 8.5 8.5 Rajasthan 34 17 18 8.5 9.5 Karnataka 32 16 17 8 9

Therefore, average number of literate males in a state = (9 + 12 + 12 + 8.5 + 10 + 8.5 + 9.5 + 9)/8 = 981250
