Answer» $\huge\bold{\underline{\underline{Answer}}}$ LET the 5 RS. note be x. Let the 10 Rs. note be 10+x AMOUNT of 5 Rs. = 5 × x . Amount of 10 Rs. = 10(x+10) *Total = 1000* $\textsf{5x+10(x+10)=1000}$ $\textsf{5x+10x+100=1000}$ $\textsf{15x+100=1000}$ $\textsf{15x=1000-100}$ $\textsf{15x=900}$ x = $\sf\frac{900}{15}$ $\huge{\boxed{\boxed{x=60}}}$ 5 Rs *Note* be 60. 10 Rs *note* be 10+60 = 70.
