Question

two numbers A and B are such that the sum of 6% of A and 5% of B is two_third of the sum of 8%of A and 10% of B. find the ratio of A:B​

Answer 1

Answer:

5 : 2

Step-by-step explanation:

6% of A + 5% of B = 2/3 (8% of A + 10% of B )

1/100( 6A + 5B) = 1/100*2/3(8A + 10B)

18A + 15B = 16A + 20B

2A = 5B => A/B = 5/2

thus A : B = 5 : 2
