उत्तर

15% increase in price of an article, which is Rs 1,620, is the increase of Rs 212.

Explanation:

Let the price of the article be Rs. x.

After 15% increased in price, price became Rs. 1620

So, `1620 = x + x xx 15/100`

⇒ `1620 = (115x)/100`

⇒ 115x = 1620 × 100

⇒ `x = (1620 xx 100)/115`

⇒ x = Rs 1408

Hence, increase in price = Rs. 1620 – Rs. 1408 = Rs. 212
