Option 3 : Rs. 750 and Rs. 1350

**Given**

Ratio of cost price of balloons and candles = 1 : 1

Ratio of market price of balloons and candles = 2 : 3

Market price of balloons = Cost price of balloons + 20% of cost price of balloons

**Calculation**

Cost price of balloons = (1/2) × 1500

⇒ 750

Cost price of candles = 1500 - 750

⇒ 750

Market price of balloons = 750 + 20% of 750

⇒ 750 + 150

⇒ 900

Let the total market price is Rs x

⇒ (2 /5) × x = 900

⇒ x = (900 × 5)/2

⇒ x = 2250

Market price of candles = 2250 - 900

⇒ 1350

**∴ The market price and cost price of candles are Rs.1350 and Rs 750.**
