However, like any other online service, users may sometime...Solution: Total number of invalid votes = 15 % of 560000. = 15/100 × 560000. = 8400000/100. = 84000. Total number of valid votes 560000 – 84000 = 476000. Percentage of votes polled in favour of candidate A = 75 %. Therefore, the number of valid votes polled in favour of candidate A = 75 % of 476000. = 75/100 × 476000.Problems. Consider the following three data sets A, B and C.
