How many centimetres more should Chandra Pal jump to equal the Men's World Record for high jump?

Answer 1

We know
1 m = 100 cm
Men's world record for high jump = 2 m 45 cm
= 2 m + 45 cm
= (2$\times$100) cm + 45 cm
= 200 cm + 45 cm
= 245 cm
High jump record of Chandra Pal = 2 m 17 cm
= 2 m + 17 cm
= (2$\times$100) cm + 17 cm
= 200 cm + 17 cm
= 217 cm
Now, we will subtract 217 cm from 245 cm.

$\begin{array}{ccccc}& 2& 4& 5& \mathrm{cm}\\ -& 2& 1& 7& \mathrm{cm}\\ & 0& 2& 8& \mathrm{cm}\end{array}$

Thus, Chandra Pal should jump 28 cm more to equal the men's world record for high jump.
