Question

Q12) I have Rs 1000 in ten and five rupee
notes. If the number of ten rupee notes
that I have is ten more than the
number of five rupee notes, how many
notes do I have in each denomination:​

Answer 1

Answer:

5 x 60 = 300

10 x 70 = 700

300 + 700 = 1000

Answer 2

$\huge\bold{\underline{\underline{Answer}}}$

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.
