Question
What was the price of House P last year? I. The
ratio of the price of two houses P to Q was 3:4 last year. II. This year, the price of houses P has increased by 20% and that of house Q by Rs 20,000. III. This year the ratio of the price of house P to house Q is 4:5. In each of these questions, one question is given followed by by data in three statements I, II and III. You have to study the question and data in the statements and decide that the question can be answered with the data given in which of the statements and mark your answer accordingly. ÂSolution
From I, II and III Let the price of two houses A and B be 4x and 5x respectively. (3x × 120/100)/(4x + 20,000) = 4/5 18x = 16 x + 80,000 18 x - 16 x = 80,000 2 x = 80,000 x = 40,000 Last year the price of house P was 40,000 × 3 = Rs 1,20,000 Hence all the statements together are required to answer the question.
