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?
The correct answer is A. 45
25% of 100 = 25 pests
â´ Number of remnants = 100 - 25 = 75 pests
40% of 75 = 30 pests
Total pest remaining = 100 - (25 + 30) = 100 - 55 = 45 pests
