what is c.p​

Answer 1

Answer:

hope it help

Step-by-step explanation:

S.P= Rs. 1440

profit=20%

C.P=?

we know

profit=(S.P-C.P)×100%÷C.P

20= (1440-C.P)×100%÷C.P

20=144000-100C.P÷C.P

Do cross multiply

20C.P=144000-100C.P

20C.P+100C.P=144000

120C.P=144000

C.P=144000÷120

C.P=Rs.1200

Therefore the cost of a chair is Rs. 1200

Answer 2

Answer:

C.P= R.s 1200

Step-by-step explanation:

S.P= 1440

Profit of 20%

C.P= S.P- Profit

C.P= 1440- 20% of C.P

1440= C.P+20/100xC.P

1440= [1+1/5]xC.P

1440=6/5xC.P

1440x5/6= C.P

1200=C.P
