CAT 2007 Solutions Section I 1. Note that the price of Darjeeling tea remains constant after the 100th day (n=100). If the prices of the two varieties of tea become equal before n = 100‚ then 100 + 0.1n = 89 + 0.15n ∴ n = 220‚ which is not possible. (Since n has been assumed to be less than 100) ∴ The prices of the two varieties will be equal after n = 100‚ i.e.‚ when the price of Darjeeling tea = 100 + 0.1 × 100 = 110 ∴ 89 + 0.15n = 110 ∴ n = 140 2007 is not a leap year.
