Can you tell what will be the sum of the fourth row ?

i.e. Sum of Burger + Beer Bottle * Beer Mug ?

obviously you have to apply some mathematics here, question is how fast you can solve it.

**Answer**: 15

**Solution**:

If you see there are 3 variables and 3 equations, we can solve the equations and get the variables values and than we can find the value of fourth equation.

From the first equation we can say that Beer Bottle = 10

than from the second Burger = (20 – 10)/2 = 5

and from the third equation Beer Mug = (9 – 5)/4 = 1

Thus Burger + Beer Mug * Beer Bottle = 5 + 1*10 = 15

here as per BODMAS 5 + 1*10 will be 5 + 10 and not 6*10
