a) End of Y1 = 102% = $5,610
Beginning of the year = 100% = 5,610 / 1.02 = $5,500

b) 40% of the money AFTER receiving the interest = 40% x 5,610 (instead of 5,500) = $2,244
This same amount of money is used to buy a fridge at 15% discount i.e. selling price of fridge at 85% = $2,244. So what is 100%?

100% = 2,244 / 0.88 = $2,550
