Question

If the price of a pencil and an eraser be ₹ x and ₹ y respectively. Find an algebraic expression for the price of 3 pencils and 2 erasers.

• A. 3x + 2y
• B. 2x + 3y
• C. 6xy
• D. xy + 6

Answer 1

The correct option is A 3x + 2y

​

Price of a pencil = ₹ x​

So, price of 3 pencils = 3 × x = 3x​

Price of an eraser = ₹ y​

Price of 2 erasers = 2 × y = 2y​

Total price = price of 3 pencils + price of 2 erasers = 3x + 2y​

​Answer: (A) 3x + 2y
