N7,840
N6,250.00
N616.00
N5,833.33
Correct answer is B
I = \(\frac{PRT}{100}\)
100(A - P) = prt
P = \(\frac{100A}{100 + RT}\)
= \(\frac{100 \times 7000}{100 + (4 \times 3)}\)
p = \(\frac{700,000}{112}\)
= N6,250.00
N2,000.00
N4,000.00
N6,000.00
N10,000.00
Correct answer is A
Total amount invested by A and B = N5,000
farm yield was sold for N15,000.00
profit = 15,000.00 - 5,000.00
= N10,000.00
Profit was shared in ratio 2 : 3
2 + 3 = 5
A received \(\frac{2}{5}\) of profit = \(\frac{2}{5}\) x 10,000 = N4,000.00
A receive \(\frac{3}{5}\) of profit = \(\frac{3}{5}\) x 10,000 = N6,000.00
Difference in profit received = N6,0000 - N4,000.00
= N2,000.00
6 : 5
25 : 24
5 : 6
24 : 25
Correct answer is D
Length and width of a square is 100%
Length increased by 20% and
Width decreased by 20% to form a rectangle
Length of rectangle = 120% to form a rectangle
Length of rectangle = 120% and
Width of rectangle = 80%
Area of rectangle = L x W
Area of square = W
Ratio of the area of the rectangle to the area of the square
A = \(\frac{\text{Area of rectangle}}{\text{Area of square}}\)
\(\frac{120 \times 30}{100 \times 100}\) = \(\frac{96}{100}\)
= 24 : 25
55.00km/h
60.00km/h
67.50km\h
75.00km\h
Correct answer is C
Average speed from P to Q = 90km\h
Average speed from O to P = 45km/h
Average for the entire journey = 90 + 45
\(\frac{135}{2}\) = 67.50 km/h
0.8
0.9
1.1
1.2
Correct answer is C
\(\frac{0.021741 \times 1.2047}{0.023789}\) = \(\frac{0.022 \times 1.2}{0.024}\) (to 216)
= \(\frac{0.0264}{0.024}\)
= 1.1
