Please help me solve this problem:


If Larry give $12 to Alice, he will have five times as much as Alice. If Alice gives $12 to Larry, she will have 1/3 of the amount Larry has. How much money does Alice have at first?

Hi

You may wish to check your question from the source again.

It's more logical if it is phrased as \"If Larry give another $12 to Alice, he will have three times as much as Alice.\"

Hi

“After each pupil in the class had received 3 stickers and 8 stamps from Mr. Lim,”

This means ratio of stickers:stamps ------- 3:8

\"The number of stickers was half as many as the number of stamps.\"

This means the number of stamps is twice the number of stickers.

Hence,2(3units+39) ------ 8units+2

After each of them bought a hand phone of the same price, Bala had three times as much money left as Ivan. How much did the hand phone cost?
