    Oops.

    2.5 maybe. 2.5^2.5 is in the vicinity of 10(9.88)

    Now it is clear, the solution or near correct solution is by trial and error as indicated by your response. I don’t have the correct answer but usual method of taking log on both sides to baseten doesn’t help to get the right answer. It is clear the answer is close to 2 +some decimal value. Ie two plus some fraction.
    Thanks for your attempting the solution.
    Regards.

    I tried this later last night. The solution for x log x = 1 comes up to something like x≈2.50618414 which when raised to itself is 9.999999. 2.5 seems good enough and it was easy to deduce!

    Thanks for helping me recall some basics!

    :hello:Mr A drops his spouse S daily by car to her office in the morning and pick her up for return home from her office in the evening at 5; and reach home at a particular time every day.

    on a particular day, Office of S closed early at 4 and therefore she - to save boredom began walking in the direction of home and met her hubby in car en route.

    When they reached home, it was observed they had reached home twenty minutes earlier.
    What was the time When they met and for how long S walked?

    Sir - I learned this in high school. I didn’t attend business school. I don’t possess any business savvy in me.
