Question

A man bought 2220 mangoes at ₦5x. he sold each for 3x kobo and made a gain of ₦8. find the value of x​

Answer 1

x = 0.1299

Explanation:

They bought the 2220 mangoes at, Buying Price = ₦5x

Now,

1 ₦ = 100 kobo

also, they sold each for 3x kobo,

so,

The total money they made was,

Selling Price = (2220)(3x)

Selling Price = 6660x (in kobo)

Now,

If we subtract the buying price from the selling price, we get the gains or profit,

So,

Selling Price - Buying Price = Gains

So, Converting all into ₦,

Divide selling price by 100 to get it into naira (₦)

so,

Selling price = 66.6x

So,

Selling Price - Buying Price = Gains

66.6x - 5x = 8

61.6x = 8

x = 10/77

x = 0.1299
