Question

In a long jump competition, jumps of four boys are marked as follows.

$\begin{array}{cc}\text{Name}& \text{Distance jumped}\\ \text{Sudhir}& 4\text{m}20\text{cm}\\ \text{Raghav}& 3\text{m}70\text{cm}\\ \text{Somesh}& 4\text{m}50\text{cm}\\ \text{Tarun}& 3\text{m}90\text{cm}\end{array}$

What is the difference between the longest jump and the shortest jump?

• A. 15 cm
• B. 50 cm
• C. 80 cm
• D. 90 cm

Answer 1

The correct option is C 80 cm

Longest jump is by Somesh, which is 4 m 50 cm.
Shortest jump is by Raghav, which is 3m 70 cm

$4\text{m}50\text{cm}=400\text{cm}+50\text{cm}=450\text{cm}$

$3\text{m}70\text{cm}=300\text{cm}+70\text{cm}=370\text{cm}$

Difference between the longest jump and shortest jump
= 450 cm - 370 cm
= 80 cm
