# 15% increase in price of an article, which is Rs 1,620, is the increase of Rs _________

**Solution:**

If a price on article is Rs. 100 then an increase of 15% in the price result into new price of:

Rs. 100 + 15% of 100

= Rs. 100 + (15/100) × 100

= Rs. (100 + 15)

= Rs. 115

Therefore if the price of an article is Rs.1620, after a 15% increase then original price would be:

Original price = (100/115) × 1620

= (20/23) × 1620

= Rs. 1408.70

Therefore the increase in price is Rs. 1620 - Rs. 1408.70 = Rs. 211.3

**✦ ****Try this:** 20% increase in price of an article, which is Rs 1,440, is the increase of Rs _________

Original price = (100/120) × 1440

= 120 × 12

= Rs. 1200

The increase in price is Rs. 1440 - Rs. 1200 Rs. 240
