In the figure, PS bisects angle QPR. Find the ratio SR:QR.

A.
1:2 
B.
1:3 
C.
1:4 
D.
1:5 
E.
1:6
Correct Answer: Option C
Explanation
From Internal bisection theorem, (frac{QP}{PR}) = (frac{QS}{SR})
= (frac{4}{1})
= 1:4
From Internal bisection theorem, (frac{QP}{PR}) = (frac{QS}{SR})
= (frac{4}{1})
= 1:4
