44. Siti, Rahmesh and Peter had 528 stickers at first. Siti bought another 32 stickers, Rahmesh gave 1/5 (one fifth) of his stickers away and Peter was given as many stickers as he had at first by his father. In the end, all three of them had equal number of stickers. Find the number of stickers Siti had at first. (The answer provided is 192 stickers and the working did not seem right) Can someone explain? Thanks.

Hi Stella,

Yes .. there's something wrong with the numbers given in the question (most likely due to some typo error).

Well, how about if you change this statement " ... Siti bought another 32 stickers ... " into " ... Siti bought another 22 stickers.... " ?

Try this and I think you will be able to get something.

//Updated 21May
If you are using the number of stickers bought by Siti as 22 (as suggested above) , the answer will be 178.

Note:
Total Number of Marks for this whole paper (on the 1st page) was changed to 95. Believed this 5-mark question was taken out then.

Cheers,

Yes, something is wrong. Change it to Siti bought another 33 stickers or 22 stickers as what the other person said. Then it is divisible by 11.

528 + 33 = 561
561 / 11 units = 51
51 x 4 = 204
204 - 33 = 171.

The answer given is wrong. It is incorrect to divide by 10 units as it did not take into account the 1/5 unit that Ramesh had given away.
