  3. Some questions have problems.

    Q5 The answer is 60/21, which calculates to 2.857.
    So the nearest answer is •Approx 3 days not •Approx 2days.

    Q5 The question has one condition missing. According to the given conditions, all the answers are correct. How can you ask the share of P after just giving the ratio?

    Q19 Sum of temperatures = 42
    Difference of temperatures = 30
    x + y = 42 & y – x = 30
    Solving both equations x = 6 and y = 36
    Hence first day’s temperature is 6.
