Question: 25% of a magazine is used to sell 2nd hand cars . 62.5% of the remaining pages were used to show other things and 36 pages of them were used for advertisement ..HOW MANY PAGES ARE THERE TOTALLY??????? TIP : ONLY 17% IN THIS WHOLE WORLD GAVE THE ANSWER WRITE AS MY TEACHER SAID .IF U WANT TO BE THE 18 TH % TTTRRRRYYYYY THHHIISSSSS
Btw don't you think you have exagerrated this one like only 17% of the world solved this LoL !!
Solution:

Let the total pages= y
Percentage of pages used for selling cars= 25% of y = 0.25y
Remaining percentage= 100 - 25 = 75%
The percentage of remaining pages = 75% of y = 0.75y
62.5% of remaining pages = 0.75y x (62.5/100) = 0.46875y (Do not round this off if you want an accurate answer)
Pages for ads= 36

Therefore the equation becomes like this

0.25y + 0.46875y + 36 = y
0.71875y + 36 = y
Y - 0.71875y = 36
0.28125y=36
Y= (36/0.28125) = 128

Cheers ! I hope you'd get it !

225 ?
You were done with IGs , no ?
Yep that one.
Yes,I'm done with it.
The bearing of D from A is 090 so that angle in between is 45. Extend the line from C and that angle will be 45 too.
Bearing of A from C = 180 + 45 = 225°
Thanks!
Maybe she wants to repeat Math in the upcoming session
Haha no Alhamdulillah I'm not repeating anything.
Someone asked me to help out with this. Sadly I couldn't so that's why I'm here. :)

Thanks both!
Help is appreciated.
