Question

A cake of mass 550 g has three dry ingredients: flour, sugar and raisins.

There is twice as much flour as sugar and one and a half times as much
sugar as raisins. How much flour is there?

Answer 1

Let flour, sugar, raisins be 3x, 1.5x, x grams respectively.

Total Mass = 550g 3x+1.5x + x = 550g

5.5x = 550 x = 100g

Flour = 3x= 3 x 100 = 300g

Hence, flour in mixture is 300g
