If 0.5% of A =85 paise, then the value of A is?

Correct Answer: 5

Explanation:

Let 45 x A = (25 x 900)/100
? A = (25 x 9)/45 = 5

Correct Answer: 0.35

Explanation:

33¹/₃% = (100/3) /100 = 1/3 =0.33;
4/15 = 0.26
Clearly 0.35>0.33>0.26
? 0.35 is greatest

Correct Answer: 300

Explanation:

? 90A/100 = 30B/100 = (30/100) x AC/100
? C = 100 x (100/30) x (90/100) = 300

Correct Answer: 32

Explanation:

Required number = 80 - 60% of 80
= 80 - (60 x 80)/100
= 32

Correct Answer: 150

Explanation:

Let 31% of A = 46.5
? (31 x A)/100 = 46.5
? A = (46.5 x 100) / 31 = 150

Correct Answer: None of these

Explanation:

Required percent = [(3/100) / (5/100)] x 100]%
= [(3/100) x (100/5) x 100] %
= 60%

Correct Answer: None of these

Explanation:

Let 75% of 480 = A x 15.
? (75 x 480)/100 = 15A
? A = (75 x 480)/ (100 x 15) = 24

Correct Answer: 150%

Explanation:

Required percent = {30/(2 x 10)} x 100 % = 150%

Correct Answer: 50

Explanation:

? A - 20% of A = 40
? A - A/5 = 40
? 4A/5 =40
? A = (5 x 40)/4 = 50.

Correct Answer: x

Explanation:

Let x% of y = y% of A, then
? xy / 100 = yA/100
? A = (xy/100) x (100/y) = x
