A man bought 220 mangoes at N5x. He sold each for 3x kobo and made a gain of N8. Find the value of x

Correct answer is B

The cost price of the whole mangoes = N5x
The sold amount of the mangoes = 3x * 220 = N6.60x
The gain made on mangoes = N6.60x - N5x = N8.00 => N1.60x = N8 => \(x=\frac{8}{1.60}=\frac{1}{0.2}=\frac{10}{2}=5\)
