Lina shares some money with her sister in the ratio 3:5.Lina receives RM126 more than her sister.How much money,in RM,Lina has?
+128460 Call the amount her sister receives, A
Then Lina's amount is A + 126
And 3 : 5 means that 5/3 of her sister's money = Lina's money.....so we have
(5/3)A = A + 126 multiply through by 3
5A = 3A + 378 subtract 3A from both sides
2A = 378 divide by 2
A = RM189 ....this is her sister's money
And Lina's money = (5/3) 189 = RM 315
Check : Lina's Amount - Sister's Amount
315 - 189 = 126
