The average height of a volleyball team of 12 Brazilian
players is 185 cm. If the height of the coach is included, the average height increases by 3 cm. Find the height of the coach.Solution
ATQ, Total height of the players excluding coach = 12 × 185 = 2220 cm Let the height of the coach be ‘h’ cm. According to the question, (2220 + h) / (12 + 1) = 185 + 3 2220 + h = 13 × 188 2220 + h = 2444 h = 2444 – 2220 h = 224 cm. So, the height of the coach is 224 cm
