Two numbers A and B are such that the sum of 5% of A and 4% of B is two-third of the sum of 6% of A and 8% of B. What is the ratio of A and B? Correct Answer 2 : 3

ব্যাখাঃ প্রশ্ন অনুযায়ী, 5A/100 + 4B/100 = 2/3 ×[ 6A/100 + 8B/100] 5A + 4B = 2/3 × [ 6A + 8B] 3×[5A + 4B] = 2[6A + 8B] 15A + 12B = 12A + 16B 3A = 4B A : B = 4 : 3
