Options:
A .  12
B .  20
C .  8
D .  None of these
Answer: Option D
:
D
Based on the question we can complete the grid as follows
456810PXXXXQXXXXRXXXXSXXXXTXXXX
It is given that |S-T|=10
P=13[4+R]
T=R2
T= P+S
Let us go from answer options
1) If P=6, R=14
T=, S= T-P=1
|ST|10
2) If P=12, R=32
T=16, S=4
|ST|10
3) If P=20, R= 56,
T= 28, S=8
|ST|10
4) If P=8, R=20,
T=10, S=2
|ST|10
Hence, the answer is none of these
