Anyone knows the answer
Answer with proper steps​

Answer 1

Answer:

let the ratio be x

a=3x

b=4x

c=5x

now put the value in the given equation

(2*3x+3*4x+2*5x)/(4*3x-4x+2*5x)

6x+12x+10x/22x-4x

28x/18x

14/9

Step-by-step explanation:

sorry to say but i think option may be wrong

Answer 2

$HEYA \: \\ \\ GIVEN \: \: QUESTION \: \: Is \: \: \\ \\ \frac{a}{3} = \frac{b}{4} = \frac{c}{5} \: \: \: find \: \: \: \frac{2a + 3b + 2c}{4a - b + 2c} \: \: ...s\\ \\ \frac{a}{3} = \frac{b}{4} \\ \\ a = \frac{3b}{4 } \: \: ...i \\ \\ \frac{b}{4} = \frac{c}{5} \\ \\ c = \frac{5b}{4} \: \: ...ii \\ \\ now \: substitute \: of \: a \: and \: c \: in \: s \\ \\ \\ \frac{ \frac{6b}{4} + 3b + \frac{10b}{4} }{3b - b + \frac{5b}{2} } = \frac{ \frac{3}{2} + 3 + \frac{5}{2} }{3 - 1 + \frac{5}{2} } \\ \\ = \frac{4 + 3}{ \frac{3}{2} + 3 } \\ \\ = \frac{7}{ \frac{9}{2} } \\ \\ = \frac{7 \times 2}{9} \\ \\ = \frac{14}{9}$
