From II : Q only taller than S, so S is shortest, and Q is second shortest, Now T taller than P and R both, So tallest of all.

### Question 2

**What is the distance between point P and point Q?(l) Point R is 10 m west of point P and point S is 10 m north of point P.(ll) Point Q is 10 m south-east of point R. Point S is 20 m north-west of point Q.**

#### Correct Option: D

#### Explanations:

From I : No relation between points P and Q

From II : In this since we don’t know the angles between sides of triangle forming with points PQS and PQR, PQ cannot be determined.
