Question 1 (Method 1) The price of a scooter was Rs 34,000 last year. It has increased by 20% this year. What is the price now? Given, Old Price of scooter = 34000 Percentage increase = 20% Percentage increase = (πΌπ‘›π‘π‘Ÿπ‘’π‘Žπ‘ π‘’ 𝑖𝑛 π‘π‘Ÿπ‘–π‘π‘’)/(𝑂𝑙𝑑 π‘π‘Ÿπ‘–π‘π‘’) Γ— 100 20 = (πΌπ‘›π‘π‘Ÿπ‘’π‘Žπ‘ π‘’ 𝑖𝑛 π‘π‘Ÿπ‘–π‘π‘’)/34000 Γ— 100 20 = (πΌπ‘›π‘π‘Ÿπ‘’π‘Žπ‘ π‘’ 𝑖𝑛 π‘π‘Ÿπ‘–π‘π‘’)/340 20 Γ— 340 = Increase in price 6800 = Increase in Price ∴ Increase in Price = 6800 Now, New price = Old Price + Increase in price = 34000 + 6800 = 40800 ∴ New price is now Rs 40,800 Question 1 (Method 2) The price of a scooter was Rs 34,000 last year. It has increased by 20% this year. What is the price now? Given, Old Price of scooter = 34000 Percentage increase = 20% Increase in price = Percentage increase Γ— Old Price = 20% Γ— 34000 = 20/100 Γ— 3400 = 20 Γ— 340 = 6800 ∴ Increase in Price = 6800 Now, New price = Old Price + Increase in price = 34000 + 6800 = 40800 ∴ New price is now Rs 40,800
