This is an error from SOF side. The correct answer is 4/7 not 3/7. More confusion will be created because red looks like pink. Moreover there is problem in the typing.

Fill in the blanks.
(i) Point B is 3 spaces right and one space above from the point A(–1, –2). So point B lies in quadrant P.
(ii) Point B is 40 spaces left and 0.02 spaces above from the point A(20, 0.18). So point B lies in quadrant Q.
(iii) Point B is 15 spaces right and 15 spaces below from the point A (–15, 0). So, coordinate of point B are R.
(iv) A man moves 30 metres towards North and then moves 50 metres towards South and finally 10 metres towards East. Considering his initial position at origin, the coordinate of his final destination are S.

P Q R S
A II I (0, 15) (–10, 20)
B. IV II (0, – 15) (10, – 20)
C. II IV (10, – 20) (0, – 15)
D. I II (0, 15) (10, 20)
