➞ Profit = 528 - C.P

**Prof****it**** ****perc****ent**** ****=**** ****Prof****it****/****C****.****P**** ****×**** ****1****0****0**

➞ 10 = 528 - C.P/ C.P × 100

➞ 10 × C.P = (528 - C.P) × 100

➞ 10/100 × C.P = 528 - C.P

➞ C.P/10 = 528 - C.P

➞ C.P = 10×(528 - C.P)

➞ C.P = 5280 - 10 C.P

➞ C.P + 10 C.P = 5280

➞ 11 C.P = 5280

➞ C.P = 5280/11
