Carpet sales
A shop increased the price of carpets by 20%.
Sales of carpets dropped by 20%.
Did the shop’s profits from carpet sales rise or fall?
SOLUTIONS Bunch of grapes (ages 8 to 12) 77 grapes. The smallest number that divides exactly by 6, 8, and 9 is 72 (then 144, 216, I). So the number of grapes is 72 + 5 = 77.
Carpet sales (ages 11 to 15) Profits on carpet sales fell by 4%. The new price of carpets is 120Z100 of the old price. Sales are 120Z100 X 80Z100 X 100% = 96% of old sales.
