If 30% of A = 0.25 of B = 1/5 of C, then find the ratio of A:B:C


A) 15 : 12 : 10

B) 12 : 15 : 10

C) 10 : 12 : 15

D) 10 : 15 : 12

Correct Answer:
C) 10 : 12 : 15

Description for Correct answer:

Let the 100% of A be 100

30% of A = 25% of B .... (1)

30% of A = 30

=> B = \( \large\frac{30 \times 100 }{25} = 120 \)

Then,

30% of A = 20 % C .... (2)

\( \large c = \frac{30 \times 100}{20} = 150 \)

100 % of A = 120% of B = 150% of C

Ratio of A : B : C =10:12: 15
