Meena went to a bank to withdraw Rs. 2550.She asked the cashier to give her Rs. 10, Rs. 50and Rs. 100 notes only. She got 65 notes intotal. Also, the number of Rs. 10 notes Meenagot is three times the number of Rs. 100 notes,find the number of Rs. 50 notes that Meena got?

Answer»

$\sf{given} \begin{cases} \sf{Meena \ withdraw \ Rs. \ 2550 } \\ \sf{She \ got \ cash \ in \ <klux>NOTES</klux> \ of \ <klux>10</klux>,50,100 } \\ \sf{ Total \ number \ of \ notes = 65} \end{cases} \\$

Let the note of ₹100 be x and note of ₹10 be 3x.

again, Notes of ₹50 = (65 - x - 3x)

$\circ \ {\pmb{\underline{\boxed{\sf{ According \ to \ Question: }}}}} \\ \\ \\ \colon\implies{\sf{ 100(x)+10(3x)+50(65-x-3x) = 2550 }} \\ \\ \\ \colon\implies{\sf{ 100x + 30x + 3250-50x-150x = 2550 }} \\ \\ \\ \colon\implies{\sf{ 130x+3250-200x = 2550 }} \\ \\ \\ \colon\implies{\sf{ -70x+3250 = 2550 }} \\ \\ \\ \colon\implies{\sf{ 3250 -2550 = 70x }} \\ \\ \\ \colon\implies{\sf{ 700 = 70x }} \\ \\ \\ \colon\implies{\sf{ x = \cancel{ \dfrac{700}{70} } }} \\ \\ \\ \colon\implies{\sf{ x = 10 }} \\$
