Given:
To gain 25% after allowing a discount of 10%, the shopkeeper.
ㅤ
Find:
What must be cost the price of the article which costs him Rs 360.
ㅤ
Calculations:
→ S.P = C.P (1 - 0.1)
→ S.P = 0.9
ㅤ
→ Profit = 25/100 × 360
→ Profit = 0.25/360
→ Profit = 90
ㅤ
→ C.P = 360/90
→ C.P = 450
ㅤ
→ C.P = 450 × 10/9
→ C.P = 500
ㅤ
Therefore, 500 is the cost price of the article.
