please solve the question

Answer 1

let the number be 5x and 8x respectively.

According to question,

$\frac{5x + 12}{8x + 12} = \frac{3}{4} \\ \\ 4(5x + 12) = 3(8x + 12) \\ \\ 20x + 48 = 24x + 36 \\ \\ 20x - 24x = 36 - 48 \\ \\ \cancel{ - }4x = \cancel{ -} 12 \\ \\ 4x = 12 \\ \\ x = \frac{12}{4} = 3$

Hence , the sum of numbers 5x and 8x is

5x + 8x

=> 5 × 3 + 8 × 3

=> 15 + 24

=> 39

Option [A] 39 is correct.
