Answer 2

$\huge\mathbb{\underline{SOLUTION:-}}$

$\begin{cases}\sf{Cost\:of\:8\:pens=96Rs}\\ \sf{Cost\:of\:11\: pencils=110Rs}\end{cases}$

• We have to find the cost of 1 pen and 1 pencil

$\bf\underline{\underline{According\:To\: Question:-}}$

$\sf\implies 8\:pens\: cost=96\\ \\ \sf\implies 1pen=\cancel{\frac{96}{8}}\\ \\ \sf\implies 1\:pen\:cost=12$

$\boxed{\sf{Cost\:of\:1\:pen=12Rs}}$

• Now we have to find the cost of 1 pen

$\sf\implies 11 \:pens\:cost=110\\ \\ \sf\implies 1\:pen=\cancel{\frac{110}{11}}\\ \\ \sf\implies cosr\:of\:1\:pen=10Rs$

$\boxed{\sf{Cost\:of\:1\: pencil=10Rs}}$

$\boxed{\mathfrak{\purple{1\:pen\:cost=12Rs.}}}$

$\boxed{\mathfrak{\purple{1\:pecil\:cost=10Rs.}}}$
