$20+$2w is the correct answer… w is just the unknown variable so you can change it to any letter you may wish! Hope this helped!
3/10 *1 = 3/10 so 3/10 * (100/100) = 300/1000 = 3/10
1 3/6 = 4/6+5/6 ,
1 1/5 = 1/5 + 5/5 , 2/5 + 4/5
1 4/8 = 6/8+6/8 , 7/8+5/8
Divide 43.54 by 3.5

Answer:
let cp be x
sp= 115x/100 ---(when 15%gain)
sp = 88x/100------(when 12% loss
according to question
115x/100 - 88x/100 = 81
or, (115x-88x)= 8100
or, 27x = 8100
or, x= 8100/27
x = 300
hence cp is RS 300
