\( \Large \frac{a}{3}=\frac{b}{4}=\frac{c}{7} \), then \( \Large \frac{a+b+c}{c} \) is equal to

A) 0
B) 1
C) 2
D) 3

Correct Answer:



C) 2

Description for Correct answer:
\( \Large \frac{a}{3} = \frac{b}{4} = \frac{c}{7} = k \)

Therefore,

a = 3k

b = 4k

c = 7k

Therefore, \( \Large \frac{a+b+c}{c} = \frac{34k+4k+7k}{7k}=2 \)
