**So, this McDonalds brain teaser has kept thousands of you guessing over the last few days! **

**Did you get it right? **

We have had such a variety of answers on this, each person adamant that they are correct. So, drum-roll please – the actual answer is…

**15**.

Bearing in mind that the rule of multiplication is you always multiply first (BODMAS)…

**So,**

**1 drink =10**

**1 burger = 5**

**Only 1 fries = 1 **

**– yes?**

Therefore…

**10×1=10, + 5 = 15**

Let me know if you are one of the ‘geniuses’!

You’re using a rule no one uses and hasn’t for years. I work with complex accounting problems every day and have never encountered equations written this way; neither do I write them this way. The use of parenthesis separates the various functions. I took algebra in the late 50’s and don’t recall being taught this obscure rule. It was obviously used before someone brighter decided to use parenthesis.

This must be some kind of new math – not the way I was taught to do math 50 years ago – my answer is 60 – same as KK comment. 🙂

Answer is 25. Fries = 2 each not 1.

PEMDAS The answer is 25.

OOPS – I was wrong!!! It is 15 – Mea Culpa!

I got 15.

Each shake = 10 so 10 x 3 = 30

Each burger = 5 so 10 +5 +5 = 20

Each fry = 2 so 5 +2 +2 = 9

Last equation: 1 fry x 10 = 10 + 1 burger, 5 = 15

But each fry is worth 2, not one so 2×10=20, +5 = 25.

There are 4 fries in line 3.

Four fry boxes = 4, so one fry box = 1

In the equation they are showing 4 fries in total, making the value of the fries 1 each.

(burger) 5 + (fry) 1 x (shake) 10 = 60 (no parentheses were used to change the order of the problem so this math problem should have been straight across add, multiply then state the answer.

BODAS rule means:

Brackets, Orders (powers and roots), Division and Multiplication, … When all your operations are the same level (for example, all division or multiplication), simply work from left to right.

Drink 10

Burger 5

Fries 1 ea.

1 burger + 1 Fry = 6 x 1 Drink = 60

multiply first, then add

No, the answer is 16, not 15

10+10+10=30

10+5+5=20

5+2+2=9

5+1*+10=16

*two fries for $2.00 means 1 fries for $1.00

You must always multiply first Eileen, (BODAS rule) so I think that’s what is confusing so many of us.. I didn’t get it right!

Fries = 1? I think not.

Burger 5 + 2 fries = 9 so fries are 2 surely?

Answer is 25

The graphic shows 4 pictures of fries plus 1 burger equals nine.(each picture of fries equals 1)

One burger (5)+ 1 picture of fries(1)x 1 drink(10) = 15

d=drink

b=burger

f=fry

d+d+d=30

3d=30

d=30/3

d=10

d+b+b=20

10+2b=20

2b=10

b=10/2

b=5

b+2f+2f=9

5+2f+2f=9

4f=4

f=1

b+f*d=x

5+1*10=x

5+10=x(order of operations multiply before add)

15=x

There are 2 packs of fries which equal 2, so I pack is only 1… 😄

10+10+10=30

10+5+5=20

5+2+2=9

5+2*10(5+20)=25

I know there’s only 1 fries but doesn’t that count as 2 Because burger is 5, to get to 9, it’s 4. But there IS only 1. So surely it’s 2. Which makes the answer 25. Surely

Drink = 10

Burger = 5

Fries = 1

5+1= 6 x 10 = 60

Why is the fry only worth 1 when it is worth 2 on the previous problem?
