Answer 2

➤ Given :-

Total marbles with John :- 40

Total percent of marbles given :- 35 $\bf\%$

➤ To Find :-

Number of marbles left with John...........

➤ Solution :-

First, we should find the total number of marbles given to John's friend, because it's in percentage form we should convert it into numerical form.

$\tt \longrightarrow40 - \bigg(35 \bf\% \sf \: \: of \: \: \tt40 \bigg)$

$\tt \longrightarrow40 - \bigg( \dfrac{35}{100} \times \dfrac{40}{1} \bigg)$

$\tt \longrightarrow \dfrac{35}{ \cancel{100}} \times \dfrac{ \cancel{40}}{1} = \boxed{ \tt40 - \bigg( \dfrac{35}{10} \times \dfrac{4}{1} \bigg)}$

$\tt \longrightarrow40 - \bigg( \dfrac{35 \times 4}{10 \times 1} \bigg)$

$\tt \longrightarrow \dfrac{40}{1} - \bigg( \cancel\dfrac{140}{10} \bigg) = \boxed{ \tt\dfrac{40}{1} - \dfrac{14}{1} }$

The total marbles given to his friend is 14.

Now, we have finally find the total marbles given to his friend.

So, total marbles left with him :-

$\tt \longrightarrow \dfrac{40 - 14}{1} = \dfrac{26}{1} = \boxed{ \tt26}$

$\Huge\therefore$John is left with 26 marbles.
