13. Find the ratio of the price of a pencil to that of a ball pen if pencils cost 96 per score and ball

pens cost 50,40 per dozen,

$\huge \sf \bold {answer}$

As we know that a dozen = 12

A score = 20

Cost of 20 pencil = 96

Cost of 1 pencil = 4.8

Cost of 1 dozen ball pen = 50.40

Cost of 1 pen = 50.40 ÷ 12 = 4.2

$\therefore ratio \: = 4.8 \ratio \: 4.2$
