lurline:

Question is roughly : There are 60 apples and 75 pears. She wants to group them together with no remainder. There are same no. of total fruitsin each group. How many apples are there in each group?

1) 5
2) 4
3) 12
4) 15

ds said that the question asked 'the person wanted to have as many bags(groups) as possible'
So the correct is 4

HCF of 60 and 75 = 15
So 15 bags (max number of bags) of 4 apples and 5 pears in each bag.
Then ans is 2) 4 apples in each bag.

Questioner:

So overall is it easy ?


Most probably 90marks won't get a* right?

According to my P6 Maths teacher friend, the paper seemed harder than last year's cos it had more tricky questions.
But if the student is strong in the concepts, solving the questions wouldn't be a prob; he or she would probably lose careless marks at those tricky questions, like the //gram question.

So that means a student who is very strong in Maths will score A* if he finds the paper easy?

My kid said the options given are
1) 15
2) 12
3) 5
4) 4

He said the question was something like every bag must have the same number of one kind of fruit.

His answer is option 4 which is 4.

[quote=\"novi\"]How bt MCQ Q11: about 60 apples and 75 pears.


What's your answer?
My gal put (3)

DS put 4.

My DS put 3. Some of his classmates put 1. What is the ans?[/quote]The answer is 4.
60/4 = 15
75 can be divided by 15 with no remainder.[/quote]

Question is roughly : There are 60 apples and 75 pears. She wants to group them together with no remainder. There are same no. of total fruits in each group. How many apples are there in each group?
1) 5
2) 4
3) 12
4) 15

60/12 = 5 groups
75/15 = 5 groups

12+15 = 27 total fruits (12 apples + 15 pears in a group). So total there are 5 groups.
My DS's tuition teacher said the ans is 3.[/quote]

Apparently there are 2 correct answers - 4 and 12 apples
15 groups x (4 apples + 5 pears) ---> 4 apples --- Option (2)
5 groups x 12 apples + 15 pears) ---> 12 apples --- Option (3)

If the question stated \"to have as many bags / groups as possible\", then the answer is 4 apples, but Option (2) and not (4)![/quote]
My kid said the option 4 answer is 4. Hope he didn't see wrongly.
He also said it stated to have as many bag as possible.

[lurline]

ds said almost the whole class gets the answer 4 for this qn. they have compared answers after the papers.

[panickymum]

My gal said option 4 is 4 . Option 3 is 5

This is from the earliest post.
1) 15 (2) 14. (3) 5. (4) 4

60 x 1 75 x 1
30 x 2. 25 x 3
20 x 3. 15 x 5
15 x 4
12 x 5
10 x 6

5 bags (12 apples and 15 pears)
15 bags (4 apples and 5 pears) --- maximum number of bags

So answer is 4 apples. --- option (4)

DS also put his answer his answer as 4…
