do step by step method​

Answer 1

Given:-

• Price of an article is ₹1050.

• Increase rate in price of article is 12.5%.

To Find:-

• New price of that article ?

Solution:-

Here, Price of article is ₹1050 and,

Rate of increase is 12.5%.

So, Amount increased ⇒ ₹ ( 1050 + 1050 × 12.5% )

                                     ⇒ ₹ ( 1050 + 1050 × $\dfrac{12.5}{100}$ )

                                    ⇒ ₹ ( 1050 + 105 × 1.25 )

                                     ⇒ ₹ ( 1050 + 131.25 )

                                     ⇒ ₹1181.25

Hence, New Price of that Article is ₹1181.25

Some important terms:-

• In the condition of increase in rate = ( Original price + Original price × $\dfrac{Change\ in\ rate}{100}$ )

• In the condition of decrease in rate = ( Original price - Original price × $\dfrac{Change\ in\ rate}{100}$ )
