Question

If cost price =x

If selling price =242
If profit =z
If profit percent =10%
Find the value of z and x​

Answer 1

x= 217,6

z=24,2

Step-by-step explanation:

Answer 2

x = 220
z = 22


Step-by-step explanation:

SP = selling price
CP = cost price

Profit % = (SP - CP) / CP x 100%

10% = (242 - x) / x • 100%

10/100 = (242 - x)/x • 100/100

1/10 = (242 - x)/x • 1

1/10 • x = 242 - x

x/10 = 242 - x

x/10 • 10 = (242 - x) • 10

x = 2420 - 10x

x + 10x = 2420

11x = 2420

x = 2420/11

x = 220





Profit = SP - CP

z = 242 - x

z = 242 - 220

z = 22
