## Q&A - PSLE Math

### Re: Q&A - PSLE Math

For this case, I guess the acceptable answer should be

(a) 3km (b) 30km/h because the numbers add up with

no contradiction (except to the statement "At the same time,...")

If we assume they both started at the same time, then we

will run into total distance being both 30km and 43.5km.

What we need is a linguist to advice if "At the same time,..."

can mean that they didn't start their journey at exactly the same time.

i disagree. Also, a quick check will show 'meanwhile, while, concurrently, in the mean while and simultaneously, ...' as acceptable synonyms for 'at the same time.' More importantly, where is this question quoted from? The setter should set the record straight.BigDevil wrote:For this case, I guess the acceptable answer should be

Yes, good to know the source. We wouldn't want this question gets recycled into the school exams.alfretztay wrote:i disagree.

Hi..ps help the following questions. Many tks and God Bless:)

1) For every 3 stamps Jiahui gave to Ryan, he would always give 1 back to her.

At first, Ryan had 10 stamps more than Jiahui.

Find the difference between the number of stamps they had in the end after Jiahui had given 12 stamps to Ryan.

2) There were 180 girls and 150 boys in the Arts Theatre and 210 girls and 560 boys in the School Hall at first. After some boys and girls moved from the School Hall to the Arts Theatre, there were an equal number of boys and girls in the Arts Theatre and thrice as many boys as girls in the School Hall.

How many boys and how many girls were moved from the School Hall to the Arts Theatre?

Sorry, 2 more. Many tks and God Bless:)

1) A farmer had some geese and ducks.

If he bought another 40 ducks, the ratio of the number of ducks to the number of geese would become 5:6.

If he bought another 60 geese instead, then the ratio of the number of ducks to the number of geese would become 2:3.

How many more geese than ducks did the farmer have?

2) Three children, Sally, Lynn and Penny have different amounts of money.

The amount of money Lynn has is the total of Sally and Penny's amount.

The amount of money Penny has is the total of Sally's amount and half of Lynn's amount, Sally has $14.

(a) How much does Lynn have?

(b) How much do these three children have altogether?
