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%
Answer:
The larger angle is 52. 4
The smaller angle is 37. 6
Step-by-step explanation:
The equation is:
(x-14. 8)+x=90
x+x-14. 8=90
2x=90+14. 8
2x=104. 8
x=52. 4
The value for the larger angle is x
and x =52. 4
The value for the smaller angle is x-14. 8
and x-14. 8=52.4-14.8
=37.6
Verification
(x-14.8)+ x=90
(52.4-14.8)+52.4=90
37.6+52.4=90
90=90
Answer: 171
Step-by-step explanation:
An obtuse angle means more than 90 degrees. (90 degrees would be the inside corner of your notebook paper) a straight line would be 180 degrees. 171 is the closest to 180
