Ai Tong School P5 Math CA1 2006 (Q47)

Monica, Vanessa and Angeline share 3 packets of sweets among themselves. Each packet contains 180 sweets. Monica takes 90 sweets while Angeline takes 3 times as many sweets as the total number of sweets Vanessa and Monica receive. If Vanessa is to get the same number of sweets as Angeline, how many sweets must Angeline give to her?

Solution




4 units + 90 + 270 ----- 540
4 units ----- 540 – 270 – 90 = 180
1 unit ----- 180 divided by 4 = 45

Vanessa has 45 sweets (1 unit)
Angel has 3 units + 270 -----
(3 x 45) + 270
= 135 + 270
= 405





Angel has 405 – 45 = 360 more than Vanessa

Therefore, she has to give -----
360 divided by 2 = 180

Answer: Angeline has to give 180 sweets to Vanessa.
