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

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.

So there are 60 apples, in your words, 60/5 = 12 in each group. There should be 12 pears as well. 75/12 = X Answer is not 3.
Let's take 4 groups. 60/4 = 15
75/15 = 5 No remainder. Correct! Answer is 4.

But the question said that \"She wants to group them together with no remainder\".
So you are saying apples has 4 groups and pear has 5 groups?
I thought apples and pears are grouped together? :?[/quote]I agree with bleeze, that answer is 12 if it is really so that the question states that \"there are same number of total fruits in each group\", not \"each group has the same number of apples and pears\".

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]

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)!

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.

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?
