₦60,580
Correct answer is C
Salvage value is the estimated book value of an asset after depreciation is calculated.
Salvage value + Depreciation value = Cost price
Salvage value + 10,580 = 50,000
∴ Salvage value = 50,000 - 10,580
⇒ ₦39,420
0.25kg/day
0.2kg/day
0.5kg/day
0.125kg/day
Correct answer is D
200 layers → 25kg/day
1 layer → x
∴ \(\frac{200}{1}\) = \(\frac{25}{x}\)
200x = 25
x = \(\frac{25}{200}\) = \(\frac{1}{8}\) = 0.125 kg/day
45
50
25
75
Correct answer is A
25% of 100 = 25 pests
∴ Number of remnants = 100 - 25 = 75 pests
40% of 75 = 30 pests
Total pest remaining = 100 - (25 + 30) = 100 - 55 = 45 pests
