A300 , 400

B250 , 450

C200 , 350

D250 , 400

Answer:

B. 250 , 450

Read Explanation:

200,250,300,350,400,450,500

N = 7

Q1=(n+1)4thvalueQ_1 = \frac{(n+1)}{4}^{th} value

Q1=(7+1)4thvalue=2ndvalueQ_1 = \frac{(7+1)}{4}^{th} value = 2^{nd} value

Q1=250Q_1 = 250

Q3=3×(n+1)4thvalueQ_3 = 3\times \frac{(n+1)}{4}^{th} value

Q3=3×2=6thvalueQ_3 = 3\times 2 = 6^{th} value

Q3=450Q_3 = 450
