Hello user
Ans15..
Let the salary of C be 100
So, that of A = 100 - 20/100 × 100 = 100 - 20 = 80 ..... (1)
Also, that of B = 100 - 10/100 × 100 = 100 - 10 = 90 ......... (2)
Let A be x% of B
So, 90 × x/100 = 80
x = 8/9× 100 = 88.88
So, A is 88.88 % of B.
So , option B is correct
____________________________________________________________
Ans16...
Here , option B is correct again .
Because as we know that the product and sum of the roots of any polynomial must be a real number so the roots must exist in pair if they are imaginary because as we know that sum or product of any two imaginary number can be real if they are in conjugate pair .
So, option B is correct again here.

Hope it works
