Question

by selling a motorcycle for 23000 a dealer gain 15% find its cost price

Answer 1

23000*15/100
=3450
c p = 23000-3450
=19550

Answer 2

Let the cost price be x.
Therefore, the gain = 15/100 * x = 3x/20
As per question,
x + 3x/20 = 23000
=> 23x/20 = 23000
=> 23x = 23000 * 20
=> x = 23000 * 20 / 23
=> x = 20000
Therefore, cost price= 20000
