A trader sells an article at 16% below its cost price. Had he sold it for ₹192.20 more, he would have gained 15%. The cost price (in ₹)of the article is:

620 680 720 640

620

ATQ, 16% below the cost price = 84% of the cost price Gain of 15% means = 115% of the cost price So, (16% + 15%) of the cost price = 192.20  100% of the cost price = \(\frac{192.20 × 100}{31}\) = 620
