B.5.125 %

C.6.000 %

D.4.125 %

Explanation:

The number of men who can read and write = 150000 × (98 ÷ 100) =147000 Number of men and women who can read and write =294000 × (53 ÷ 100) =155820 Number of women who can read and write 155820 – 147000 = 8820 Thus, out of 144000 women 8820 can read and write. Required percentage = (8820 × 100) ⁄ 144000 %= 6.125

A.18.9%

B.37.8%

C.56.7%

D.75%

Question 5 If 90% of A = 30% of B and B = C% of A,then the value of C is ?

A.900

B.800

C.600

D.300

Question 9 Rajesh solved 80 percent of the questions in an examination correctly, out of 41 questions solved by Rajesh 37 questions are correct and of the remaining questions out of 8 questions, 5 questions have been solved by Rajesh correctly then find the total number of question asked in the examination?

A.75

B.65

C.60

D.Can’t be determined

Ans. B

Explanation:

Suppose there are 8y questions were asked apart from the 41 question.Then 37 + 5y/41 + 8y = 80% = 4/5 ⇒ 185 + 25y = 164 + 32y ⇒ 7y = 21 ⇒ y = 3 ∴ Total no. of questions = 41 + 8 x 3 = 65.

Question 10 The difference between 78% of a number and 59% of the same number is 323. What is 62% of that number?

A.1054

B.1178

C.1037

D.1159

E.None of the above

Ans. A

Explanation:

Let the number be N. According to the question, (78 – 59)% of N = 323 ⇒ (19 x N)/100 = 323 ∴ N = (323 x 100)/19 = 1700 ∴ 62% of 1700 = (62/100) x 1700 = 1054
