Form the equations relating to the girls according to their weight, such that Janet is 4.5kg more than S (J = 4.5 + S) and Mei Ling is 2 times heavier than Janet (ML = 2J). The total weight of the girls would be 173.9 (ML + J + S). From there, substitute in Mei Ling's weight and Janet's weight such that the only unknown left is Siti's weight and from there remove any access weight and divide it accordingly.
