The trader bought 60 goats
Solution:
A trader bought goats for N 4000 each
He sold them for N 180,000 at a loss of 25%
To find: Number of goats bought
From given,
Cost price of 1 goat = 4000
Cost price of "x" goats = 4000x
Selling price of "x" goats at loss of 25 % is:
180000 = 4000x - 25 % of 4000x
[tex]180000 = 4000x - \frac{25}{100} \times 4000x\\\\180000 = 4000x (1 - 0.25)\\\\180000 = 4000x \times 0.75\\\\0.75x = 45[/tex]
Divide both sides by 0.75
x = 60
Thus he bought 60 goats
