    help please

    13. This year Kishan gets 260 a week for his work.
    This is 30% more than his weekly pay last year.

    His friend Danny says-

    "That means you got only 182 a week last year".

    Danny is wrong.


    a)Explain why Danny is wrong.

    As for explaining what Danny did wrong, instead of realizing that 260 was 130% of the original amount, he made the error of assuming that 70% of the current payment was equivalent to 30% more than his former pay.

    So he multilplied 260*70%, and got 182. By dividing 260 by 130%, as the above poster did, you get 200, which is the correct answer.

    Hope this helps for the first half of the question!
