A man bought 220 mangoes at N5x. He sold each for 3x kobo and made a gain of N8. Find the value of x
  • A.
    2
  • B.
    5
  • C.
    6
  • D.
    10
Correct Answer: Option B
Explanation

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)
