Question

How many students have their height less than 140 cm ?

• A. $31$
• B. $32$
• C. $33$
• D. $34$

Answer 1

The correct option is D $34$

Number of students in $(125$ cm $-130$ cm$)=6$
Number of students in $(130$ cm $-135$ cm$)=8$
Number of students in $(135$ cm $-140$ cm) $=20$
So, total number of students less than $140$ cm. $=20+6+8=34$
