Hi,


I need help for the following questions:

1.\tIn a competition consisting of 30 problems. Lydia was given 12 points for each correct solution & 7 points were subtracted from her score for each incorrect solution. Problems not attempted contributed 0 points. How many correct solutions did Lydia have if her score was 209? (Hint : 19 X 11 = 209).

2.\tDiana is to go for a business trip. She needs a collection of wigs and sunglasses, 8 items altogether. At least 3 of these have to be wigs and at least 4 sunglasses. She has 10 different wigs and 12 different sunglasses to choose from. In how many ways can she organize the collection of wigs and sunglasses she needs for the trip.

TIA.

Thx for d alternative solution, Absolutely Bo Chap.

Thank u v much, Maths Olympiad Tutor for yr clear explanation:)

Hi all, pls help on the following 2 qns:


1) If x & y are positive integers which satisfy x² - 8x - 1001y² = 0, what is
the smallest possible value of x + y?

2a) If y = |x| + |x + 1| + |x - 1|, find the minimum value of y.

b) Find the area, in square units, enclosed by the figure whose boundary
points satisfy |x|+ |y|=4

TIA.
