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
<u><em>Answers:</em></u>
AD = 10 units
BD = 12 units
<u><em>Explanation:</em></u>
<u>1- getting AD:</u>
In an isosceles triangle, the two non-parallel sides are equal.
It is given that trapezium ABCD is isosceles which means that AD = BC
<u>We are given that:</u>
BC = 10 units
<u>Therefore:</u>
AD = BC = 10 units
<u>2- getting DB:</u>
In an isosceles trapezium, the diagonals are congruent
Since the given trapezium is isosceles and AC and BD are its diagonals, therefore:
AC = BD
<u>We are given that:</u>
AC = 12 units
<u>Therefore:</u>
BD = AC = 12 units

I believe you mean "greater" not "theater".
If this is true, than 7 over 8 is greater than 2/3.
Hope this helps! :)
