The bar graph given below shows the production of truck by two companies in five years.

Bar graph of trucks produced by companies A and B: Y1 300 and 350, Y2 600 and 600, Y3 550 and 450, Y4 700 and 800, Y5 800 and 400.

Which of the following statement is NOT correct?

I. The production of truck by A in year Y1 is 50 percent of the production of truck by B in year Y2
II. The ratio of the total production of truck by B in year Y4 and Y5 to the total production of truck by A in Y2 and Y3 is 24 : 23

  • A.Only I
  • B.Only II
  • C.Both I and II
  • D.Neither I nor II

Answer: D

Statement I says A's production in Y1 is 50 percent of B's production in Y2. A produced 300 in Y1 and B produced 600 in Y2, and 300 is 50 percent of 600, so statement I is correct. Statement II says the ratio of B's total in Y4 and Y5 to A's total in Y2 and Y3 is 24 : 23. B produced 800 + 400 = 1200 and A produced 600 + 550 = 1150, and 1200 : 1150 = 24 : 23, so statement II is also correct. The question asks for the statement that is NOT correct, and neither statement is wrong, so the answer is Neither I nor II, option (D).
