What is the total number of votes polled if B got 128 votes?

A. 400 Wrong Right

B. 240 Wrong Right

C. 204 Wrong Right

"/> D. 332 Wrong Right

Answer : 332

Explanation : Let total voters be 100x. Hence, 3/5th i.e. 60x promised to vote for A and 40x for B.
15% of 60x = 9x did not cast their vote for A
20% of 40x = 8x did not cast their vote for B
Hence, A got 51x votes and B got 32x votes.
32x = 128

7x – 6 = 4x + 6
3x = 12
x = 4
Therefore, (7x + 12) / (4x – 12) = (7*4 + 12) / (4 * 4 -12) = 40/4 = 10/1
