20=4
x

and what aboujt percentages when they ask you: (somebody) bought a car for 6000 but then sold it for 6600... how much percente did he get after selling it???? Its something like that... but reply really soon

ok i'll call u and let u know

ahsan u should start POSTING your answers so that if any1 else has a similar question they would be able to figure it out by just reading your posts xD

less calling and more posting plz

ok his answer was simple
1: 20=4/x
.
. . 20x= 4
.
. . x= 0.2

2: origal price: 6000
increase price: 6600
.
. . 6600/6000= x/100
(cross mutiply)
.
. . 660,000= 6000x
.
. . x=110

x % -100 % = increase %#
.
. . 110-100= 10% increase

(cheack) 6000 X (110/100) = 6600 √
