As Q is mid point of PS so PQ = QS

and PQ=7(Given) so QS=7

and QS= QR+RS => 7=QR+4 => QR=3

PR= PQ+QR=> 7+3= 10

OA B

\(PQ = 7, PS = 14, QS = 7.\)

\(QS = QR + RS\)
\(RS = 4, QR = 3.\)

\(PR = PQ + QR\)
\(PQ = 7, QR = 3, PR = 10.\) Ans - B.

Since PQ+QR+RS=14 [Q being mid point of the segment so PR=2PQ]
Substituting and solving for QR above would give 3. PQ+QR=10.
So answer is B.
