The average height of three boys, Marks, Lewis and Khairul is 1 m and 62 cm. If mark is 150 cm tall and lewis is 163 cm tall, how tall is khairul? Give your answer in cm.

Answer 1

Let the height of Khairul be x cm.

According to the given information:
(Mark + Lewis + Khairul) / 3 = 1 m 62 cm = 162 cm

(150 + 163 + x) / 3 = 162
(313 + x) / 3 = 162
313 + x = 3 * 162
313 + x = 486
x = 486 - 313
x = 173

Therefore, Khairul is 173 cm tall.
