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

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: 2% of AB

Explanation:

A% of B + B% of A =AB/100 + AB/100
= 2AB/100 = 2% of AB

Correct Answer: 111.1

Explanation:

? A = 90% of B
? A = (90 x B)/100
Let C% of A = B
Then, (C x A)/100 = B
? [C x {(90 x B)/100}] / 100 = B
? C = (100 x 100) / 90 =111.1

Correct Answer: None of these

Explanation:

Let 8% of 96 = y of 1/25
? (8 x 96)/100 = y/25
? y = (8 x 96 x 25)/100 = 192

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: 5

Explanation:

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

Correct Answer: Rs. 170

Explanation:

? 0.5/100 of A = 85/100
? A = Rs. (85 / 0.5) = Rs. 170

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
