ATQ, Let the average height of a person in group 'L' = 'c' cm. Then, the average height of a person in group 'K' = (c - 14) cm. Total height of all people in group 'L' = 18 × c = '18c' cm. Total height of all people in group 'K' = 22 × (c - 14) = 22c - 308 cm. So, 22c - 308 = 18c. Or, 4c = 308. So, c = 308 / 4 = 77. Required average height = 77 cm.
