Answer:
Let the MP of 1 article = Rs 1
MP of 15 article = Rs 15
SP of (15+1) articles = 15 x 96/100
= Rs 14.40
CP of 16 article = 14.40/135 x 100
= Rs 32/3
CP of 1 article = 32/3x16
= Rs 2/3
Required % = 1/3 x 3/2 x 100
= 50

We have x^2 - 2·4·x + 4^2 + 5 = ( x - 4 )^2 + 5.
Then, h = 4 and k = 5.
-0.0833333333 Should be the answer
I kind a get the answer for this one but I’m not sure if that’s the correct one but I think your answer will be -6
