Gain per cent is $13 \frac{1}{3} %$ $13 1/3%$

As articles are bought at Rs.45 per dozen,

unit buying rate is $\frac{45}{12} = \frac{15}{4} = R s .3 .75$ $45/12=15/4=Rs.3.75$

As they were sold at Rs.85 per score,

unit selling rate is $\frac{85}{20} = R s .4 .25$ $85/20=Rs.4.25$ .

As such there is a gain of $4.25 - 3.75 = R s .0 .50$ $4.25-3.75=Rs.0.50$ on each $R s .3 .75$ $Rs.3.75$ .

and gain per cent is $\frac{0.50}{3.75} \times 100 = \frac{50}{375} \times 100 %$ $0.50/3.75xx100=50/375xx100%$

= $(2cancel50)/(cancel15^3cancel375)xx20cancel100%$

= $40/3=13 1/3%$

$13 1/3%$

You need to know that a dozen is $12$ and a score is $20$

Find the unit price in each case.

$12$ articles cost $Rs45 " "rarr 45/12 = Rs3.75$ each

$20$ articles sold at $Rs85 " "rarr 85/20 = Rs4.25$ each

The amount of gain per article is $Rs4.25 - Rs3.75 = Rs0.50$

The percent gain is: $0.5/3.75 xx 100% = 13 1/3%$
