Finding New Price After a Percentage Increase
A step-by-step animated board solution showing how to calculate a price after a 15% increase on Rs. 800. The animation reveals each line progressively: converting the percentage to a fraction, calculating the increase amount, and adding it to the original price to get the final answer of Rs. 920. Useful for Grade 9-10 students learning percentage applications in everyday commercial math problems.

The prompt that made it
Create a clear step-by-step animated mathematics solution for a school student. Problem: A product costs Rs. 800. Its price is increased by 15%. Find the new price. Show the solution step by step, as if a teacher is writing the working on a classroom board. Step 1: Write: 15% = 15/100 Step 2: Write: Increase in price = 800 × 15/100 = Rs. 120 Step 3: Write: New price = 800 + 120 = Rs. 920 Important: Do not show all the working at once. Reveal each line gradually, one step at a time. Use clean handwritten-style mathematical writing. Keep the previous working visible while the next step is written. Clearly highlight the final answer: Rs. 920. Use a simple white classroom-board/paper background. Make the mathematics large and easy for Grade 9–10 students to read. Do not add unnecessary graphics or characters. Use accurate mathematical notation. Create a 30–45 second educational animation with a calm teacher-style voiceover explaining each step.
