Question

22. Mona is in her garden jumping on stones (as shown below).

Answer 1

$\large\green{\sf\boxed{Given:-}}$

Mona starts from 68th stone

She jumps 23 stones ahead

Then she jumps 28 stones back

$\large\red{\sf\boxed{To \:find:-}}$

Her final position=?

$\large{|\underline{\mathtt{\red{S}\blue{o}\orange{l}\pink{u}\blue{t}\purple{i}\green{o}\red{n}\blue{:}\orange{-}}}}$

• Add 23 in 68 [Given]

$\begin{gathered}\\ \sf\longmapsto 68+23=91\end{gathered}$

• Subtract 28 from 91

$\begin{gathered}\\ \sf\longmapsto 91-28=Her\:final\:position\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto =63\end{gathered}$

• To find how much stones she is ahead or back we will Subtract 63 from 68 which was her initial position.

$\begin{gathered}\\ \sf\longmapsto 68-63=5\end{gathered}$

So, Mona will be 5 stones behind from the starting stone.

☯️Hence, Option C is correct
