Question

Mr. Gupta spends 78% of his salary. If his salary is

₹ 12750 per month, what amount does he save?

Pls Answer Step by Step​

Answer 1

➤ Given :-

Percent of salary spent :- 78%

Total salary of Mr. Gupta :- ₹ 12750

➤ To Find :-

Total amount saved by Mr. Gupta.........

➤ Solution :-

First, we should find total salary spent by finding 78% of 12750, and then we should subtract the obtained answer with total salary..........

Total salary spent :-

${\tt \longrightarrow 78 \bf\% \sf \: \: of \tt \: \: 12750}$

${\tt \longrightarrow \dfrac{78}{100} \times 12750}$

${\tt \longrightarrow \dfrac{78}{ \cancel{100}} \times \cancel{12750} = \dfrac{78}{2} \times 255}$

${\tt \longrightarrow \dfrac{78 \times 255}{2} = \dfrac{19890}{2}}$

${\tt \longrightarrow \cancel\dfrac{19890}{2} = \boxed{\tt Rs \: \: 9945}}$

Now,

Total salary saved :-

${\tt \longrightarrow 12750 - 9945}$

${\tt \longrightarrow Rs \: \: 2805}$

$\Huge\therefore$ Mr. Gupta saves ₹ 2805 from her salary every month.
