## 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.

b) Calculate Kishan's real weekly pay last year..

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!
