Answer: The price of garri has fallen by 16% overall.
Step-by-step explanation:
If the price of garri rose by 40%, it means that the new price is 140% of the original price. If the price then fell by 40%, it means that the new price is 60% of the 140% price. To find the overall change in percentage, we can multiply these percentages together:
140% x 60% = 84%
This means that the final price is 84% of the original price, which is a fall of 16% overall.
