If 100 pieces of pests is attacking an hectare of cocoa farm and 25% suddenly died while 40% of the remnant is sent for medical examination. What is the number of pest remaining?
Akọwa Nkọwa
Let's first find out how many pests there were before 25% died. If 100 pests are attacking an hectare of cocoa farm, and 25% of them suddenly died, then 100 * 25/100 = 25 pests died. So, before 25% of the pests died, there were 100 pests. And after 25% died, there were 100 - 25 = 75 pests left. Next, let's find out how many pests were sent for medical examination. If 40% of the 75 pests that were left were sent for medical examination, then 75 * 40/100 = 30 pests were sent for medical examination. So, the number of pests remaining after some were sent for medical examination is 75 - 30 = 45 pests. Therefore, the answer is 45 pests.

An increase in supply of agricultural produce can be caused by the following factors except
Akọwa Nkọwa
An increase in supply of agricultural produce can be caused by a variety of factors such as reduced cost of production, favorable weather conditions, and reduced taxation. However, the factor that does not contribute to an increase in supply is consumers buying less products. When consumers buy less products, it creates a surplus of the unsold produce and reduces demand for it. When demand for a product decreases, the market price for the product decreases as well, which can lead to a reduction in the supply of that product. In this case, the decrease in consumer demand would actually lead to a decrease in the supply of agricultural produce, rather than an increase.

The effects of practicing crop rotation include the following except
Akọwa Nkọwa
The option that does not describe the effect of practicing crop rotation is "adding humus to the soil." Crop rotation involves planting different crops in a specific sequence in a certain area over time. The purpose of this is to maintain and improve soil fertility, control soil erosion, and prevent the build-up of pests and diseases. By rotating crops, the soil is given a chance to rest and recover nutrients that were taken away by previous crops, leading to healthier soil and better crop growth. On the other hand, adding humus to the soil involves adding organic matter such as compost, leaves, or manure to the soil. This helps to improve soil structure, water retention, and nutrient availability. While adding humus to the soil can complement the effects of crop rotation, it is not a direct result of practicing crop rotation.
