Question

If Ramesh had ₹ 700 left after spending 80% of her money, how much did she have in the beginning? / अगर रमेश के पास अपना 80% पैसा खर्च करने के बाद ₹ 700 बचा था, तो शुरुआत में उसके पास कितना था?

Answer 1

$\sf{\sf{\purple{\underline{\underline{Given :}}}}}$

• Money left = Rs. 700

• Money spend = 80%

$\sf{\sf{\purple{\underline{\underline{To\:Find :}}}}}$

• Total money = ?

$\sf{\sf{\purple{\underline{\underline{Solution :}}}}}$

So finally, ⠀⠀⠀⠀

⋆ Total percentage = 100%

⠀⠀⠀⠀

⋆ Spend percentage = 80%

⠀⠀⠀⠀

⋆ Money left's percentage = 100 - 80 = 20%

⠀⠀⠀⠀

• Let us assume that the total money be x.

⠀⠀⠀⠀⠀⠀⠀⠀⠀

Now,

⠀⠀⠀⠀

$\sf :\implies \: 20\% \: of \: x = 700$

⠀⠀⠀⠀

$\sf :\implies \: \dfrac{20\times x}{100} = 700$

⠀⠀

$\sf :\implies \: { x = \dfrac{700\times 100}{20}}$

⠀⠀⠀⠀

$\sf :\implies \:{ x = \dfrac{70\times 100}{2} }$

⠀⠀⠀⠀

$\sf :\implies \:{ x = {35\times 100}}$

⠀⠀⠀⠀

$\sf :\implies \:{ x = 3500}$

⠀⠀⠀⠀

$\sf :\implies \:{\sf{ Total\: amount = x = Rs. \:3500 }}$

⠀⠀⠀⠀

${\underline{\therefore{\sf{Total \: money \: Ramesh \: had \:was\: \textsf{\textbf{Rs 3500}}}}}}$
