(A) is the correct option.Here 23 is the most frequent observation (Frequency=3), so it is the mode.Arranging the data in an ascending order, 20,21,21,22,23,23,23,24,25; so here 23 is the middle-most observation,thus it is the median of the following data.

The options are wrong because if you read the questions carefully,they said that : How many minimum number of times he made 90 degree turns . The answer should be 1 because if he walks 5 blocks (excluding P) starting from P and then goes downwards only 2 blocks then he reaches point U by taking only one 90 degree turn.

Given below are the steps of construction to construct a quadrilateral ABCD where AB = 3.5 cm, BC = 5.5 cm, CD = 2.4 cm, AD = 6.3 cm and ∠A = 45°. Which of the following steps is INCORRECT ?
Step I : Draw AB = 3.5 cm and construct ∠BAX = 45°.
Step II : With A as centre and radius AD = 6.3 cm, cut off AD = 6.3 cm along AX.
Step III : Join BD. With D as centre and radius 2.4 cm, draw an arc.
Step IV : With B as centre and radius 2.4 cm, draw an arc to cut the arc drawn in above step at C. Join BC, CD to obtain the required quadrilateral ABCD.
