A Maths Question!

Post by Drastic Dad »

We are a bit confused about following question:

A box of chocolates contains 20 chocolates of which 8 are plain chocolates. If 16 of the 20 have soft centres, what can you say about how many plain chocolates there are with soft centres?

Please help all you maths gurus. I gave up on Maths 20 years ago. Will help you in VR if you help me in Maths :lol:

20 - 16 = 4

There are at least 4 plain chocolates with soft centres I think!

I would say at least half of the dark chocs (4) will have soft centres.

I think this is a ratio question. 16:20 or 4:5 of 20 is soft chocolates. What is 4:5 of 8? I think it can be rephrased as 4/5th of 8!

4:5 of 8= 4/5 x 8= 32/5= 6.4 which rounds up to 6. Am I right???

Sorry I don't think you can approach this with ratio -

My guess

At least 4 of the plain chocolates have soft centers.

Please help all you maths gurus. I gave up on Maths 20 years ago. Will help you in VR if you help me in Maths :lol:

2/5 of the box are plain chocolates and 4/5 are having soft centres and according to the ratio 2/5 divided by 4/5 are the soft centred chocolates which are nothing but 1/2 of the plain that means 1/2x8=4.

so 4 are soft centred chocolates.

You are right. 4 is the answer. I was wrong and reading too much into it!
