Answer:
Therefore A is the answer.
Explanation:
As the triangle is proportional. One of them is enlarged of the other.
So lets find the equal sides:
here x is QP so it is similar to JK, if the other sides are equal:
⇒ x = (8*5)/10 = 4
and
⇒ ( 8*3)/6 = 4
Here in A,
if cross multiplied,
x = (8*5)/10
x = 4
