A. 4.4 cm
B. 6.8 cm
C. 8.8 cm
D. 7.7 cm

Answer 1

Correct Answer - A
Given, the height of the bar corresponding to football is 13.6 cm
Then, the height of the bar corresponding to volleyball `=(34)/(68)xx13.6=6.8cm`
the height of the bar corresponding to badminton `(56)/(68)xx13.6=11.2cm`
Therefore, the required difference =11.2-6.8=4.4 cm
Hence , the correct option is (a).
