      Solution

      From statement I, 50/100 * (SP of mobile + TV) = 5400 + SP of mobile SP of mobile + SP of TV = 10800 + 2SP of mobile SP of TV - SP of mobile = 10800 SP of mobile = 60000 – 10800 = 49200 So, Statement I alone is not sufficient to answer the question. From statement II, CP of mobile = 40x MP of TV = 125/100 * SP of mobile SP of TV = Rs.5100 So, Statement II alone is not sufficient to answer the question.
