A
2
B
5
C
6
D
10
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
The cost price of the whole mangoes = N5x
The sold amount of the mangoes = 3x * 220 = N6.60x ( 660x converted to naira by dividing by hundred.)
The gain made on mangoes = N6.60x - N5x = N8.00 => N1.60x = N8 => \(x=\frac{8}{1.60}=\frac{1}{0.2}=\frac{10}{2}=5\)
