Correct answer: C. 10 : 12 : 15
Explanation
Let each equal k. A = k/0.3 = 10k/3, B = k/0.25 = 4k, C = 5k. Multiplying by 3: A : B : C = 10 : 12 : 15.माना प्रत्येक = k। A = k/0.3 = 10k/3, B = k/0.25 = 4k, C = 5k। 3 से गुणा करने पर A : B : C = 10 : 12 : 15।More Mathematical Reasoning and Aptitude questions
