Answer:
Rs 19.20
Step-by-step explanation:
Buying price = Rs 20

Answer:
We can predict the vertex point of 
by vectorial sum, which is equal to 
.
Step-by-step explanation:
The vertex of is equal to the vectorial sum of the vertex of 
and the translation vector:
(1)
Where 
is the translation vector.
If we know that 
and 
, then the formula for the vertex of is:
It would be: 5/17 * 3/8 = 5*3 / 17*8 = 15/136
In short, Your Answer would be 15/136
Hope this helps!
