Answer:
Marked Price =MP=550 Marked Price =MP=550
Selling Price=SP=550-10%=550-55=495Selling Price=SP=550-10%=550-55=495
The profit earned is , SP−Profit=CP(CostPrice)The profit earned is , SP−Profit=CP(CostPrice)
CP=495−75=420CP=495−75=420
The difference of MP and CP is 550−420=130The difference of MP and CP is 550−420=130
The percentage of difference w.r.t CP is The percentage of difference w.r.t CP is
130420×100=30.95%

Answer:
34
Step-by-step explanation:
First we need to do 2/3*21, which equals 14 as 3 and 21 can be simplified to 1 and 7. 7 * 2/1= 14. Then we add the 20 to 14, 20+14= 34
3x−2y=12;−3x+8y=−6
Step: Solve3x−2y=12for x:
3x−2y=12
3x−2y+2y=12+2y(Add 2y to both sides)
3x=2y+12
3x

=
2y+12
