✪ ||Solution|| ✪

$profit\: in\: a\: pen = Rs.8$

$= Rs.640$

$loss \:on \:a \:pencil = 50paise$

= ₹0.5

$no. \:of\: pencil\: sold = Rs.640 ÷ Rs.0.5$

$= 1280$

Answer 2

${\orange{\underline{\underline{\bf{\bigstar \: \: Solution \: \: \bigstar}}}}}$

Profit in a pen = 38

Profit in a pen = 38 Profit in 80 pens = 38 x 80 = 3640

Profit in a pen = 38 Profit in 80 pens = 38 x 80 = 3640 Loss on a pencil = 50 paise

Profit in a pen = 38 Profit in 80 pens = 38 x 80 = 3640 Loss on a pencil = 50 paise = 0.5

Profit in a pen = 38 Profit in 80 pens = 38 x 80 = 3640 Loss on a pencil = 50 paise = 0.5 Number of pencil sold = 5640

= 30 . 5

= 1280
