If 39% of first number is equal to eight-ninths of second number, what is the ratio of first number to the second number?

Correct option is D

Given:

39% of first number (A) = \frac{8}{9} of second number (B)

Solution:

​$$\frac{39}{100}A = \frac{8}{9}B$$​​

(39 × 9)A = (8 × 100) B

351A = 800B

​$$\frac{A}{B} = \frac{800}{351}$$​​

So, the ratio of first number to second number:

A : B = 800 : 351
