Mister Yeo's model is correct, but there is a slight blip. Justin's savings is 5/9 of Ahmad's.

Oh. I read it as Justin savings to Ahmad. Thanks for the correction Xavier.

No problem, mate. Your model is spot on. If one uses fractions, one does not even need to draw a model. By equating 3/5 of Justin's savings to 3/9 of Admad's savings, we can straight away see that the ratio of Justin's savings to Ahmad's savings is 5:9.

Doing in the above-mentioned manner will be very useful for MCQ and Section B questions since you can get the answer just by inspection.

After removing 67 coins from Jace, C and J will each have an equal number of coins and C will then has $37.20 more than J. As a 50-cent coin is 40 cents more than a 10-cent coin, $37.20 means C has 93 coins. 93x$0.50=$46.50 So C has $46.50
