In a certain game, a large bag is filled with blue, green, purple and red chips worth 1,5,x and 11 points each, respectively. The purple chips are worth more than the red chips. A certain number of chips are then seleted from the bag, If the product of the point values of the seleted chips is 88,000, how many puriple chips were seleted?

A 1
B 2
C 3
D 5

Correct Answer: 2

এখানে, 88000 = 88×1000 = 8×11×1000 = 23×11×8×125 = 23×11×23×53 = 26×53×11 = 2×2×2×2×2×2×5×5×5×11 Purple চিপস এর মূল্য Green চিপস থেকে বেশি কিন্তু Red চিপস থেকে কম। অর্থাৎ 5x≠10 অতএব, x = 8 হবে। কারণ 8 = 2×2×2 যেখানে 2 কে 8 এর উৎপাদক আকারে প্রকাশ করা যায়। তাহলে ২টি Purple চিপসকে নেওয়া যাবে।
