Question

Hi, please help to solve this question.  Thanks.

Answer

This is a Before After question.

     Before  transfer  After 
 Blue  4u – 3u 1u
Green  4u – 48  – 2u + 24 2u – 24 
Pink  4u + 10   4u + 10  
Total     7u – 14

7u – 14 = 315

7u = 315 + 14 = 329

1u = 329 ÷ 7 = 47

4u = 4 × 47 = 188

188 + 10 = 198

😊

Note

We start with Blue because blue is comparing with green and pink.

We start with 4u because 3/4 of the blue is sold.
