Question

The price of 1 kg oranges is thrice the price of 1 kg apples. Which of the following linear equation represents the given statement ?
(Assume the the price of 1 kg oranges to be x and of 1 kg apples to be y)

• A. x - 3y = 0
• B. 2x + 1 = y
• C. x + 3y = 0
• D. 3x - y = 0

Answer 1

The correct option is A x - 3y = 0

Given, the price of 1 kg of oranges is x and that of 1 kg of apples is y.

According to the given condition, the price of the 1 kg oranges is three times the price of the 1 kg apple.
So, x = 3y.
Therefore, x - 3y = 0
