Btw don't you think you have exagerrated this one like only 17% of the world solved this LoL !!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
Yeah man nice oneBtw 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 !
How did u get that 0.28125Btw don't you think you have exagerrated this one like only 17% of the world solved this LoL !!

See there mate.How did u get that 0.28125
Thanks !
To be honest, I loved solving math papers. That'swhy I started from 1990s. Sounds crazyThanks !
Btw how many past papers did you do for igcse phy , Chem , bio and maths ? ( from which year till which which year ?)
No probThanks !

All variants ?To be honest, I loved solving math papers. That'swhy I started from 1990s. Sounds crazy

question 2 part c ii of
http://papers.xtremepapers.com/CIE/Cambridge IGCSE/Mathematics (0580)/0580_s03_qp_4.pdf
Explanation needed.Please and thank you!
sorry I meant part i360 -(x-45)
x was 130 so ;
=360 -( 130-45)
=360-85
=275
225 ?sorry I meant part i
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.sorry I meant part i
Maybe she wants to repeat Math in the upcoming session225 ?
You were done with IGs , no ?
Yep that one.225 ?
You were done with IGs , no ?
Thanks!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°
Haha no Alhamdulillah I'm not repeating anything.Maybe she wants to repeat Math in the upcoming session
Oh ok nevermindYep that one.
Yes,I'm done with it.
Thanks!
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.
