GIVEN DATA
125 135 160 146 135 140 154 170 110 140
N = 10
MEDIAN : MIDPOINTS OF DATA AFTER ARRANGING ASCENDING ORDER
110 125 135 135 140
140 146 154 160 170
MEDIAN = (140+140) / 2 = 140
QUARTILE 1 Q1 = MEDIAN OF LOWER HALF OF DATA
110 125 135 135 140
MEDIAN = Q1 = 135
QUARTILE3 Q2 = MEDIAN OF UPPER HALF OF DATA
140 146 154 160 170
MEDIAN = Q2 = 154
HENCE Q1 = 135 Q2 = 154
IN GIVEN DATA 152 OBSERRVATION NOT GIVEN
NOTE : I THINK 154 IS MISTAKELY TYPED AS 152 IF IT IS TRUE OPTION B IS CORRECT
