  • Question
  • The price of commodity X increases by 40 paise every year, while the price of commodity Y increases by 15 paise every year. If in 2001, the price of commodity X was Rs. 4.20 and that of Y was Rs. 6.30, in which year commodity X will cost 40 paise more than the commodity?


  • Options
  • A. 2010
  • B. 2011
  • C. 2012
  • D. 2013

  • Correct Answer
  • 2011 

    Explanation

    Suppose commodity X wil cost 40 paise more than Y after Z  years. Then,

            (4.20 + 0.40Z) - (6.30 + 0.15Z) = 0.40

    =>  0.25Z = 0.40 + 2.10  => Z= 2.50/0.25 = 10

    Therefore, X will cost 40 paise more than Y 10  years after 2001 . i.e in 2011
