Question

Hi I need help with this question. Thank you!

Mrs Lee baked 84 muffins and Mrs Tan baked 260 muffins. How many muffins did Mrs Lee have to bake so that she will have twice as many muffins as Mrs Tan?

Answer

260 x 2 = 520
520 – 84 = 436

Ans : 436 more muffins.

This is a Before After question.  

    Before    Transfer    After     
Lee   84 + 1u 84 + 1u  
Tan 260   260   

(84 +1u) / 2 = 260

84 + 1u = 260 × 2 = 520

1u = 520 – 84 = 436
