Answer:
Step-by-step explanation:
no.of pens=10
cp of i pen=x cp of 5 pens =5x
profit.A=25% of c.p= 0.25*5x=1.25x
profit= sp -cp
or, 1.25x=sp-5x
sp=6.25x
2nd condition
loss . amount= 0.833x
loss=cp -sp
or,0.833x=5x-sp
sp=4.17x
sp1+sp2=625
or,6.25x+4.17x=625
x=59.98 or 60
cost price of i pen is Rs 60

Answer:
of ice cream
Step-by-step explanation:
Given
Number of friends = 8
Size of ice cream = 1/6 quarts
Required
Total ice cream served
Let n represent the number of friends, s represent the size of ice cream and t represents total ice cream served;
t is calculated as thus;
![t = n * s](https://tex.z-dn.net/?f=t%20%3D%20n%20%2A%20s)
![t = 8 * \frac{1}{6} quarts](https://tex.z-dn.net/?f=t%20%3D%208%20%2A%20%5Cfrac%7B1%7D%7B6%7D%20quarts)
![t = \frac{8}{6} quarts](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B8%7D%7B6%7D%20quarts)
Divide numerator and denominator by 2
![t = \frac{4}{3} quarts](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20quarts)
Hence, she serves
in total
