1.	0 – 10, 11 – 20, 21 – 30, 31 – 40. The real lower limit of the class 21 – 30 is A) 21 B) 30 C) 20.5D) 21.5
Answer» Correct option is (C) 20.5 Classes are 0–10, 11–20, 21–30, 31–40 Difference between lower limit of next class and upper limit of class = 1. \(\therefore\) Classes converts to 0.5-10.5, 10.5-20.5, 20.5-30.5, 30.5-40.5 \(\therefore\) Real lower limit of the class 21-30 is 20.5. Correct option is C) 20.5

0 – 10, 11 – 20, 21 – 30, 31 – 40. The real lower limit of the class 21 – 30 is A) 21 B) 30 C) 20.5D) 21.5

Answer»

Correct option is (C) 20.5

Classes are 0–10, 11–20, 21–30, 31–40

Difference between lower limit of next class and upper limit of class = 1.

\(\therefore\) Classes converts to 0.5-10.5, 10.5-20.5, 20.5-30.5, 30.5-40.5

\(\therefore\) Real lower limit of the class 21-30 is 20.5.

Correct option is C) 20.5
