<em>Hi!</em>

<em></em>

<em>These can be set up as systems of equations.</em>

<em> </em>

<em>Let b = the number of birds, and let d = the number of dogs.</em>

<em> </em>

<em>b + d = 21</em>

<em> </em>

<em>2b + 4d = 76 (this is because birds have 2 legs and dogs have 4 legs.)</em>

<em> </em>

<em>You can solve this using either elimination or substitution.</em>

<em></em>

<em>Consider marking brainliest.</em>

when a pen is sold at a discount of 15%.There is a gain of rs 10.But if it is sold at 25% discount there is a loss of rs 2.Find
Svetradugi [14.3K]

When a pen is sold at a discount of 15% there is a gain of rs 10

When the pen is sold at 25% discount there is a loss of rs 2

Therefore the mark price of the pen can be calculated as follows

15% = c.p + 10 rs

25 % = c.p - 2 rs

25%-15% = 10 rs +2 rs

10% = 12 rs

10/100 = 12 rs

0.1= 12 rs

12/0.1

= 120 rs

Hence the mark price of the pen is 120 rs
