Answer 1

Total C.P=C.P+expenses=750+50=800

Profit =S.P–C.P

S.P=Profit+C.P=800+80=880

Percent profit =C.PProfit×100=80080×100=10

Loss=Percent loss=0

2) TotalC.P=C.P+expenses=4500+500=5000

Loss =S.P–C.P

S.P=Loss+C.P=1000+5000=6000

Percent loss=C.PLoss×100=Total C.P=C.P+expenses=750+50=800

Profit =S.P–C.P

S.P=Profit+C.P=800+80=880

 =50001000×100=20

Answer 2

Step-by-step explanation:

We have,

       △POS∼△ROQ

⇒  ∠3=∠4 and ∠1=∠2

Thus, PS and QR are two lines and the transversal PR cuts them in such a way that ∠3=∠4 i.e., alternate angles are equal.

Hence,       PS∣∣QR.
