Q. If an original quantity increased by 40%40\% to become 350350, what was the original quantity?\newlineChoose 1 option:\newline140140\newline7070\newline210210\newline250250
  1. Denote original quantity: Let's denote the original quantity as QQ. If QQ increased by 40%40\%, it means that the increase is 0.40×Q0.40 \times Q. The new quantity, after the increase, is Q+0.40×QQ + 0.40 \times Q, which is equal to 1.40×Q1.40 \times Q. We are given that after the increase, the new quantity is 350350. Therefore, we can set up the equation 1.40×Q=3501.40 \times Q = 350 to find the original quantity QQ.
  2. Set up equation: Now we need to solve the equation for QQ. To do this, we divide both sides of the equation by 1.401.40 to isolate QQ on one side.\newlineQ=3501.40Q = \frac{350}{1.40}
  3. Solve equation: Perform the division to find the value of QQ.Q=250Q = 250
