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
The answer is 0.305. All you have to do is move the decimal place three times to the left.

Let the medium angle be B degrees
the small angle be A degrees
the large angle be C degrees
Then
C = 2 B + 20 ..................X
5 B = A + C ..................Y
Sum of all angles
A + B + C = 180 .............Z
Applying Y in Z
5 B + B = 180
6 B = 180
B = 30
From X C = 2 x 30 + 20 = 60 + 20 = 80
From Y 5 x 30 = A + 80
150 = A + 80
150 - 80 = A = 70
Hence medium angle B = 30 degrees
the small angle A = 70 degrees
the large angle C = 80 degrees
