Answer:
SP of 8 articles =Rs 7360
Profit=15%
Now,
SP of each article =7360/8= Rs920
Wkt,
SP=CP+profit (let CP=x)
920=x+15%of CP
920=x+15÷100× x
920=x+15x÷100
920=(100x+15x)÷100
920=115x÷100
92000=115x
92000÷115=x
Therefore, x=Rs 800
CP=800(i.e Cost price of one article)
Again,
SP of 13 articles=Rs 11440
SP of 1 article=11440÷13=Rs 880
Since,SP>CP
Profit!
Profit=SP-CP
=880-800
=Rs 80
Profit%=profit÷CP×100%
=80÷800×100
=10%
Solutions
We know that a rectangle has four sides and the perimeter of a rectangle is the distance around the outside of the rectangle.The opposite sides of a rectangle are congruent To find the perimeter you have to use the formula 2 × <span>(Side A + Side B).
</span>
We have the side lengths 7.7 mm and 17.2 mm.
Solve
2 × <span>(Side A + Side B)
2 </span>× <span>( Side A (7.7) + Side B (17.2) )
</span>= (7.7 x 2) + (17.2 x 2)
= 49.6
<span>The perimeter is 49.6 mm². </span>
I would say the answer would be 29.17% because 
=29.17%
