      Question

      Three numbers β€˜A’, β€˜B’ and β€˜C’ are such

      that β€˜A’ is 40% less than β€˜B’ and β€˜C’ is the average of β€˜A’ and β€˜B’. If the sum of β€˜A’ and β€˜C’ is 350, then find the value of β€˜B’.
      A 200 Correct Answer Incorrect Answer
      B 250 Correct Answer Incorrect Answer
      C 300 Correct Answer Incorrect Answer
      D 400 Correct Answer Incorrect Answer

      Solution

      Let the value of β€˜B’ be β€˜10x’ So, value of β€˜A’ = 10x – {40% of 10x} = β€˜6x’ So, value of β€˜C’ = (6x + 10x)/2 = 16x/2 = β€˜8x’ ATQ; 6x + 8x = 350 Or, 14x = 350 Or, x = 25 So, the value of β€˜B’ = 10x = 10 Γ— 25 = 250
