# Question

Christopher had \$154 more than Ryan at first.After Christopher gave \$262 to Ryan, Ryan had 3 times as much as Christopher. How much did they have altogether?

At first: C – 1 unit + 154

R – 1 unit

In the end: C -1 part

R – 3 parts

(draw a model, you will visualize that 1 unit = 1 part + 108)

2 parts = 108 + 262

= 370

1 part = 370 / 2

= 185

4 parts = 4 x 185

= 740 (ans)

At first,
Christopher : 1 unit + 154
Ryan : 1 unit

After Christopher gave \$262 to Ryan, Ryan had 3 times as much as Christopher,
Christopher : 1 unit + 154 – 262 = 1 unit – 108
Ryan : (1 unit – 108) + (1 unit – 108) + (1 unit – 108) = 3 units – 324

3 units – 324 = 1 unit + 262
1 unit = (262 + 324)/(3 – 1) = 293
2 units + 154 = 740

Ans : \$740

This is a Before After question.

 Before Transfer After Ratio Christopher 1u + 154 -262 1u – 108 1 Ryan 1u + 262 1u + 262 3 Total 2u + 154

(1u – 108) / 1  =  (1u + 262) / 3

3u – 324  =  1u + 262

3u – 1u = 262 + 324

2u = 586

586 + 154 = 740 Ryan
