Question : If x : y : z = 2 : 3 : 4, then what is the value of 7x : 3y : 2z?
Option 1: $14:9:8$
Option 2: $18:7:12$
Option 3: $12:6:11$
Option 4: $16:9:8$
Correct Answer: $14:9:8$
Solution :
According to the question
Let k be the common multiplier
⇒ x = 2k, y = 3k, and z = 4k
Now,
7x : 3y : 2z
= 7 × (2k) : 3 × (3k) : 2 × (4k) = 14k : 9k : 8k
Simplify the equation by dividing the common factor k
⇒ $\frac{14k}{k}$ : $\frac{9k}{k}$ : $\frac{8k}{k}$ = $14 : 9 : 8$
Hence, the correct answer is $14: 9 : 8$.
