Answer 2

$\bold{\large{\red{\underline{\star\:HEY\:MATE \:\star\:}}}}$

$<b>Given:$

a : b : c = 2 : 3 : 4

$\frac{a}{2} = \frac{b}{3} = \frac{c}{4} = k \: (let)$


=> a = 2k , b = 3k , c = 4k

Given : 2a - 3b +4c = 33

=> 2 × 2k - 3 × 3k + 4 × 4k = 33

=> 4k - 9k + 16k = 33

=> 20k - 9k = 33

=> 11k = 33

=> k = 33/11

=> k = 3

Now, on substituting the value of k , we get;

a = 2k = 2 × 3 = 6

b = 3k = 3 × 3 = 9

c = 4k = 3 × 4 = 12
