 A) I only B) II and III only C) All I, II and III D) I only or II and III only

Answer:   D) I only or II and III only

Explanation:

$I.P*R*5100=P⇔R=20$

$II.P1+R1002-P-P*R*2100=400=>pR2=4000000$

$III.P*R*1100=2000=>PR=200000$

$PR2PR=4000000200000⇔R=20$

Thus I only or (II and III) give answer.
