You are applying for a job selling electronics. The interviewer asks you to answer the following questions in order to prove that you would be able to do your job effectively. A customer is purchasing last year's version of the Football Mania video game, which was originally $55. It is on a sale rack that says 60% off. The customer has a coupon for 30% off his entire purchase. He incorrectly says, "I can't believe I'm getting this for 90% off!"
A. Find the cost of the video game after the coupon.

B. What would be the cost of the video game at 90% off?

C. How would you explain to the customer that he is not getting 90% off?

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
