Charis and shermin are given money each. If Charis and shermin spend \$60 and \$30 each day respectively. Charis will still have \$600 when Shermin has spent all her money. If Charis and Shermin spend \$30 and \$60 each day respectively. Charis will still have \$1500 when Shermin has spent all her money. How much money is given to each girl?

• MATHS -

If the time periods are a and b days, respectively,

600+60a = 1500+30b
30a = 60b

a=20 b=10
So

check:
1800-20*60 = 600
1800-10*30 = 1500

600-20*30 = 0
600-10*60 = 0
