15/100 x = 495 → x = 495 × 100/15 → 26/100 x = 495 × 100/15 × 26/100 = 495 × 26/15 = 858
15 - it has 3 numbers either side of it.
First put them in order:11, 12, 13, 15, 16, 26, 26.Then use your fingers the numbers at the opposite ends:11, 12, 13, 15, 16, 26, 26.Then keep moving in11, 12, 13, 15, 16, 26, 26.11, 12, 13, 15, 16, 26, 26.Until you come to the middle:11, 12, 13, 15, 16, 26, 26.So the median is 15.
% rate:= (21/26) x 100%= 0.8077 x 100%= 80.77%
