In a survey it was found that 80% of those surveyed owned a car while 60% of those surveyed owned a mobile phone, if 55% owned both a car and a Mobile phone, What percent of those surveyed owned a car or a mobile phone or both?

A. 65%
B. 80%
C. 85%
D. 97.5%
Explanation:
Given that percentage of car owners = 80%
Percentage of mobile phone owners = 60%
Percentage of people having both car and mobile phone = 55%
Percentage of people having only car = 80 -55 = 25%
Percentage of people having only mobile phone = 60 -55 =5%
Percentage of people having car or mobile phone or both = 55% + 25% + 5% = 85%

In an examination, every candidate took physics or mathematics or both 65.8% took physics and 59.2% took mathematics the total number of candidates was 2000. How many candidates took both physics and mathematics?

A. 750
B. 500
C. 250
D. 125
Explanation:
Let x% candidates take both the subjects.
Therefore, Percentage of candidates who opted physics = 65.8%
And percentage of candidates who opted mathematics = 59.2%
Therefore, x =(65.8 + 59.2 – 100)%
= (125 -100)% = 25%
Also total number of candidates = 2000
Therefore, Number of candidates who opted both the subjects = 25/100 x 2000 =500

In a company, 60% of the employees are men, of this 40 % are drawing more than Rs. 50000 per year. 36% of the total employees of the company draw more than Rs.50000 per year then what is the percentage of women who are drawing less than Rs. 5000 per year?

A. 70%
B. 60%
C. 40%
D. 30%
Explanation:
Total number of employees be 100
Then number of men = 6000/100 = 60
Number of women = 4000/100 = 40
Therefore, number of men drawing more than Rs. 50000 = 2400/100 = 24 men
Since the number of total employees drawing more than Rs. 50000 = 3600/100 = 36
Number of women who draw more than Rs. 50000 = 36- 24 = 12
Number of women who draw less than Rs. 50000 = 40 -12 = 28
Therefore, Percentage of the women who draw less than Rs. 50000 per year = 28/40 x 100% = 70%

In a company, 60% of the employees are men, of this 40 % are drawing more than Rs. 50000 per year. 36% of the total employees of the company draw more than Rs.50000 per year then what is the percentage of women who are drawing less than Rs. 5000 per year? Read More »

A. 8
B. 10
C. 15
D. 16
Explanation:
Let the marks of each question be 10
Total marks got by the candidate = 8 x 5 =40 marks
40% = 40 : 100 = 100
Therefore, Total number of questions = 100/10 =10

Mathematics Mcqs, Percentage Mcqs /
Candidates in a competitive examination consisted of 60% men and 40% women 70% men and 75% women cleared the qualifying test and entered the final test where 80% men and 70% women were successful? Which of the following statements is correct?

A. Success rate is higher for women
B. Overall success rate is below 50%
C. More men cleared the examination than women
D. Both ‘A’ and ‘B’
Explanation:
Let there are 100 persons in which 60 men and 40 women number of men who cleared the qualifying test
= 70 x 60/100 = 42
Number of women who cleared the qualifying test
= 40 x ¾ = 30
Number of men who get success in final test
= 42 x 4/5 = 33.6
Number of women who get success in final test
= 30 x 70/100 = 21
Hence more men cleared the examination than a woman.
