Answer 1

Answer:

3. S. P = 9,200

profit%=15

profit = 9,200*15/100=1, 380

C. P = S. P- profit

= 9,200-1, 380=7, 820

4. (i) S.P = 2,640

profit% = 10

profit = 2,640*10/100=264

C. P = S. P - profit = 2640-264=2, 376

(ii) C. P= 2,376

profit% = 15%

profit= C. P*profit%/100( from the formulae profit%= profit/C.P*100)

profit = 2,376*10/100=237.6

S. P = C. P+profit = 2376+237.6=2,613.6

I hope my answer helps you ☺☺

Answer 2

Answer:

3, 800.

Step-by-step explanation:

sp= 9200

profit= 15%

let the cp be x.

cp+profit%of cp= sp

x + 15% of x=9200

x+15/100x=9200

115x/100=9200

x=8000

now do as same to get answer of 4as well.

but in (ii);

let the sp be y.

profit%=15%

cp( as came from (i).

hope it helps.
