Answer» Let the number of strawberries in the basket at the beginning ben. Number of strawberries eaten by Anita and her friends before the arrival of 8 girls = (5 + 3) = 8 Total number of remaining strawberries in the basket = (n– 8) Number of strawberries taken by 1stgirl = 1 Number of strawberries taken by 2ndgirl = 3 Number of strawberries taken by 3rtgirl = 5 Number of strawberries taken by 4thgirl =7 Number of strawberries taken by 5thgirl = 9 Number of strawberries taken by 6thgirl =11 Number of strawberries taken by 7thgirl =13 Number of strawberries taken by 8thgirl =15 Total number of strawberries taken by 8 girls = 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 = 64 ∴n– 8 = 64 ⇒n= 64 + 8 = 72 Thus, number of strawberries in the basket at the beginning = 72.
