Correct Answer: 0.94
Explanation:
Let A - 6% of A = AB.
? (94 x A) / 100 = AB
? B = 0.94
Correct Answer: 1500
Explanation:
Let 371/2% of A = 900
? {(75/2) x A} x 100 = 900
? A = (900 x 2 x 100) / 75 = 2400
So, 621/2% of A = (125/2) x (1/100) x 2400 =1500
Correct Answer: 48
Explanation:
Let 12.5% of 192 = 50% of A,
?(12.5 x 192) / 100 = (50 x A) / 100
? A = (12.5 x 192) / 50 = 48
Correct Answer: x
Explanation:
Let x% of y = y% of A, then
? xy / 100 = yA/100
? A = (xy/100) x (100/y) = x
Correct Answer: 50

? A - 20% of A = 40
? A - A/5 = 40

Percentage slump in business = {(A/5)/A} x 100 % = 20%
