## 11+ maths paper help!

(24 Posts)despite my A at GCSE i can't help dd with this question from an 11+ practice paper...

6 lollies and 3 ice creams cost £8.52

3 ice creams and 6 drinks cost £9.24

What would be the cost of 1 lolly, 1 ice cream and 1 drink?

TIA!

add it all together- 6 ice creams 6 lollies and 6 drinks cost 8.52 plus 9.24

then divide by 6 to find cost of 1 of each

oh fgs thank you.

here's what i was trying...

6l + 3i = 8.52

3i + 6d = 9.24

so 6l -8.52 = 3i

etc etc

You were trying to find the cost of the individual items, (as might be asked in a GCSE question, though impossible from what's been given) rather than the cost of a single set of the 3 items.

That got me confused too! I always jump in with the simultaneous equation type method for those sorts of questions, but this one is more logic in a way - I hate the phrase 'think outside the box' but it's that kind of thing!

I would have tried to overcomplicate this with simultaneous equations too.

Crumbs, that doesn't tell you the cost of each!

They're not asking for the cost of each. Just the total cost of 1 of each.

But it looks like lollies and icecreams combined cost less than icecreams and drinks combined?

I don't think you can do it without another "line" of facts......is there a typo?

Add the two sums together and divide by six (as the two sums are fir six lollies, six ice creams and six drinks).

PS My 7 year old got it immediately.

OP do you have the answer sheet for this? I would love to know the 'official' answer! My DD is doing 11 + in September...I'm not sure how she would find this question

**Alpha** your answer sounds good and makes sense.

Well Well it seams you are clearly uneducated and should go and do your GCSE again. Anything under an A* is absolutly preposterous. The answer is so obvious I don't see how you can miss it. All my children got A* in practice GCSE papers under 9 years old. You must start in year 1 again.

It's not really a maths question, it's a verbal reasoning question with a bit of simple addition and simple division thrown in.

Just to throw my 2p in (don't worry, it won't add to the total )...

If you suppose a lolly costs 90p then an ice cream will be £1.04.

If the ice cream is £1.04 then the cost of a drink will be £1.02.

That was without sitting do equations, it was by starting of by assuming the lolly was £1 and seeing if the remaining amount was divisible by 3. It wasn't so I dropped the amount by 10p and that worked.

*doing*

I agree that there is a missing line. We need to know the cost of one item in order to know the cost of each item. It just doesn't make any sense otherwise.

IT DOESNT ASK FOR THE COST OF EACH INDIVIDUAL ITEM!!!! It asks for the total cost of one of each, so how much altogether would an ice cream, a lolly and a drink cost. Not how much is an ice cream; how much is a lolly and how much is a drink.

ALRIGHT!

I was perfectly aware that it was for all three but was suggesting a different way of working it out, because not all children work things out the same way.

Sorry looks i was responding to imperial!

Dividing the first equation by 6 gives you

one lolly + half an ice = £1.42

Ditto second equation

one drink + half an ice = £1.54

Add the two new equations together

one lolly + one drink + one ice = £2.96

(a variation on what alpha said)

It sometimes pays to second-guess the examiner, they do like their integers. I noticed that both the currencies divided by six so I went with that and then it sort of fell into place from there.
