Answer:
Let, the c.p be x.
Given,
profit % = 20%
S.P = rs 816
c.p = x
We know,
profit = p% of c.p
= 
* x
= 
now,
C.p = profit + s.p.
x = + 816
x = 
5x = x + 4080
5x-x = 4080
4x = 4080
x = 
x = Rs 1080
Hence, the c.p is Rs. 1080
The answer is 15%

please mark as brainliest
The answer would to this question would be 16/40 or 40%.
Second statement is more postulate you can't prove it, so the statement is clearly a thrm.
Answer:
No, it is not possible to obtain zero by adding two vectors of unequal magnitudes.
Explanation:
The Sum of two vectors can only be zero if they are equal in magnitude and opposite in direction. So no two vectors of unequal magnitude cannot be added to give a null vector. Three vectors of equal magnitude and making an angle 120 degrees with each other gives a zero resultant.
