In a certain election race, all of the 8,400 votes were cast for either candidate A or candidate B. If votes for candidate A and votes for candidate B were cast in a 4 to 3 ratio, how many votes were cast for candidate A?

A. 1,200
B. 2,400
C. 4,800
D. 6,000
E. 8,400



A:B = 4:3.


8400/ 7 * 4
= 4800

C is the answer.

Solution


Given:
    • Total number of votes casted = 8400
    • Ratio of votes casted for candidate A to candidate B = 4: 3

To find:
    • The number of votes casted for candidate A

Approach and Working:
    • We know that A + B = 8400 ……. (1)
    • And, \(\frac{A}{B} = \frac{4}{3}\)
      o This implies, \(B = \frac{3A}{4}\)

Substituting in equation (1), we get,
    • \(A + \frac{3A}{4} = 8400\)
    • \(\frac{7A}{4} = 8400\)
    • Thus, \(A = \frac{(4 * 8400)}{7} = 4800\)

Therefore, the number of votes casted for candidate A = 4800

Hence, the correct answer is Option C

Answer: C

4 - candidate A
3 - candidate B

So votes of candidates combined is 7.

Hence, the ratio of votes for candidate A compared to the total amount of votes is:

4:7

So 4/7th out of the 8400, would give us the total amount of votes for candidate A.

4/7 * 8400 = 4800.
