At first, David --> 15 units (LCM of 3 & 5)fxchow:
Hi,
Please help on this P6 math. TIA
If David after giving 1/3 of his money to Ken, Ken will have $70 more than David.
If David after giving 1/5 of his money to Ken, Ken will have $10 money than David. How much does David have initially?
IF David give 1/3 (=5 units) to Ken,
David --> 10 units
Ken --> 10 units + $70
Ken, at first --> 5 units + $70
If David give 1/5 (=3 units) to Ken,
David --> 12 units
Ken --> 8 units + $70
Ken will have $10 more than David
so, 8 units + $70 = 12 units + $10
1 unit --> $15
At first, David --> 15 x $15 = $225
cheers.
Hi MathIzzzFun,
Thanks for you reply.
I still can't figure out the below statement.
8 units + $70 = 12 units + $10
Why 12 units + $10? and why both side is equal?
Sorry for so many questions. -

Hi MathIzzzFun,
Hi fxchow,fxchow:
Hi,
Can someone help to solve these two questions. TIA
1) Mrs Gopal and Mrs Ari went to the supermarket.
Both women decided to spend all their money on either apples or pears and they would not buy the same fruit.
If Mrs Gopal bought only pears, she would have 9 more fruit than Mrs Ari.
If she bought only apples, she would have 41 more fruit than Mrs Ari.
How much more money has Mrs Gopal than Mrs Ari?
Ans: $12
2) Talik was given some pocket money for recess. He realised that if he had spent $0.80 on each meal, he would have 8 meals fewer than if he had spent $0.60 per meal.
Talik spent $0.60 on 8 meals and spent $0.80 on the remaining meals. How many meals did the money last him?
Ans: $26
Q1 is missing some information - costs of fruits for eg.
For Q2,
If Talik spent $0.60 per meal, he would have 8 more meals ---> 8 x 0.60 = $4.80. This amount was accumulated from spending $0.20 less per meal. So, number of $0.80 meals = $4.80 / 0.20 = 24
Amount of money he had = 24 x $0.80 = $19.20
After spending 8 x $0.60 meals, number of $0.80 meals he could have
= ($19.20 - $4.80) / $0.80
= 144 / 8
= 18
Total number of meals ($0.60 meals + $0.80 meals) = 8 x+ 18 = 26
cheers.
Sorry, for question 1, each apple costs $0.40 while each pear costs $0.60.
Thanks! -

RE: How to grow cactus indoor?
kayatoaster:
the gold coated metal is it like a piece of sticker, slightly bigger than a stamp size? are cactus really effective in adsorbing radiation? any type or got specific one?[/quote]Hi kayatoaster,fxchow:
[quote=\"sall\"]Some types of cactus need direct sunlight and these will not grow well indoor, unless it's placed near the window with direct sunlight. It's better to choose forest cactus as they do not need direct sunlight, water sparingly. I'm not so convinced about cactus being able to absorb radiation, but I've also heard of this before.
Hi sall,
Thank you for your sharing.
I like cactus and heard of it can absorb radiation so decided to put one near my computer. At the same time, i can look at the \"green\" when my eyes are tired.
Talk about radiation, my colleague just bought a piece of gold coated metal costs $20 and pasted it on the monitor to absorb radiation.
The gold coated metal is a sticker which has the size of a 10cent coin. -

They thrive quite well if placed next to window. My colleague used to have 10 pots growing on her window sill in the office.
Hi jtoh,
Thanks for your sharing.
Wow! so many pots of cactus in your office. That's good, a pleasant working environment. -

How to grow cactus indoor?
Hi,
Does anyone put a small pot of cactus on your office table to absorb computer radiation?
If yes, may I know how you take care of the cactus to let it grow healthy? TIA
