Explanation:

Correct option:1

Solution: As per given statements the direction diagram is as follows:

Let H denote Rinky's house, P denote post office: M denote market and S denote school.
Then, OM = NP = 50 m and ON = MP = 150 m
OH = 150 - 70 = 80
By Pythagoras theorem, SH² = √HO² + SO²
Therefore, SO² = √170² - 80² = √22500 and SO = 150 m.
MS = 150 - 50 = 100 m
Hence, MS = air distance between the market and Rinky's school = 100 m.
