Question

a person gained 20 % by selling an article for ₹240 at what price must he sell it to gain 10%​

Answer 1

Answer:

₹220

Step-by-step explanation:

S.P-₹240

C.P-x

Profit-20℅

S.P= 20%*x +x

240=20/100*x+x

240=20/100*x+100/100

240=120/100*x

240*100/120=x

200=x

Now, for 10%

C.p=200

S.P= 10/100*200+200

=20+200

=₹220

Answer 2

Answer:

220

Step-by-step explanation:

SP=Rs240

P=20%

CP=?

P%=SP - CP ×100÷CP

20=240-CP×100÷CP

20CP=24000-100CP

120CP=24000

CP= 24000÷120

CP=RS200

10=SP-200×100÷200

2000=100SP-20000

22000=100SP

SP=22000÷100

SP=RS220
