Mathematics Challenger

I will give some craziest and mind hunter mathemetical quests. If you thinking that I am genius in mathemetics then prove your skills here,
Mind Crasher Challenge 1 :
Once a mathematician went to buy some stationaries in the shop. He purchased four different things of different prices. The total bill for him was 71.10Rs. After looking at the bill the mathmatician amazed that the summation of all prices & multiplication of all prices are same. Then what are the prices of four items?
Number Teaser Challenge 2 :
By using only 0-9 digits with the help of simple arithmetic instructions (+,-,*,/,(,),) make the number 2009

    Number Teaser Challenge 3 :
    Repeat challenge 2, but this time you have to use only subtraction, multiplicatio, & brackets.
    Sequence Catcher Challenge 4 :

    Looks like puzzles are to hard to solve. So I am giving hints for some.
    Hint for puzzle 3,
    (digit 1-8) - 9 = 2009

    Hint for puzzle 4,
    The series is related with calculator.

    My patient is over now:sad:, so here I am posting the answer.
    Challenge 3:
    1 * 2 - ( 3 - 4 - 5 ) * 6 * 7 * 8 - 9 = 2009
    Challenge 4:
    #->>> 6,2,5,5,4,5,6,4,7,5,8,...
    It is a series of segments needed to show the number in calculator. For example, to display 0 we need 6 segments. For 1 we need 2, so on.
    I am living challenge 1 as a real challenge for CEans.
    Don't you have dare to solve the challenge?
    Its an open challenge for you all CEans out there!!!!
    All the best for it.👍
