Hi there,


Anyone can help me on following 5 very challenging questions, thanks in advance :boogie:

Qn 4. Ali had $190 more than Baba at first. After Baba had spent $50, Ali had 4 times as much money as Baba had left. How much did Ali have at first?

After Baba spent $50,
Ali would have ($190 + $50) = $240 more than Baba

$240/3 = $80
Ali's money --> $80 x 4 = $ 320

cheers.

Qn 5. Charlie and Mr Brown had the same number of buttons. If Charlie gives 500 buttons to Mr Brown, Mr Brown would have 6 times as many buttons as Charlie. How many buttons did Charlie have at first?

After giving 500 buttons to Mr Brown, Charlie would have 500x 2 = 1000 less buttons than Mr Brown.

Charlie's buttons left = 1000/5 = 200
Charlies's buttons at first = 200 + 500 = 700

cheers.

Appreciate if anyone can help me in the following two questions. :?


Qn1. Amos and Lynn have 120 pears altogether. After Amos gave 17 pears to Lynn, they each have the same number of pears.
(a) How many pears do they each have at the end?

120 / 2 = 60
[quote](b) How many pears does Amos have at first?[/quote]In the end, Amos has 60 pears after giving away 17 pears.
Therefore, at first, Amos has (60 + 17) = 77 pears.

Is this really a P4 question :?
