Show answer & explanation
Correct answer: B
B's income is 40% less than C's income, so B = 60% of C = 0.6C.
Therefore, C = B / 0.6 = 1.6667B.
Percentage by which C is more than B = (C - B)/B × 100.
= (1.6667B - B)/B × 100 = 66.7% (approximately).
The information about A is not needed for this particular question.
