ATQ, Let the average height of a person in group 'J' = 'b' cm. Then, the average height of a person in group 'I' = (b - 18) cm. Total height of all people in group 'J' = 30 × b = '30b' cm. Total height of all people in group 'I' = 36 × (b - 18) = 36b - 648 cm. So, 36b - 648 = 30b. Or, 6b = 648. So, b = 648 / 6 = 108. Required average height = 108 cm.
