ATQ, Let the average height of a person in group 'H' = 'a' cm. Then, the average height of a person in group 'G' = (a - 12) cm. Total height of all people in group 'H' = 24 × a = '24a' cm. Total height of all people in group 'G' = 28 × (a - 12) = 28a - 336 cm. So, 28a - 336 = 24a. Or, 4a = 336. So, a = 336 / 4 = 84. Required average height = 84 cm.
