Please help with the following question. Tnx.Roger was twice as heavy as Sean and thrice as heavy as Terrence. Given that total mass of the 3 boys was 121kg, how much heavier was Roger than Terrence. Leave your answer in kilograms.

(Notice that R is repeated, hence, we make R the same in both sets of ratio and form a relationship) R : S R : T 2 : 1 3 : 1 6 : 3 6 : 2 Summary R : S : T 6 : 3 : 2 Total = 6u + 3u + 2u = 11u 11u = 121 1u = 11 4u = 44 Roger was 44 kg heavier than Terrence

10+10+15 = $35 $16 275 / $35 = 465 sets of 2 women + 1 men so there are 465 x 2 = 930 women
