Okay so in this expression, the variable x is set to 9.
Because this expression is just x = x, whatever the value of x is will be the same for both x's.
So, f(9) = 9
Answer:
MP = Rs. 1500
SP = Rs. 1230
Step-by-step explanation:
Let the Cost Price (CP) be x
<u>Then Market Price (MP):</u>
<u>Discounted Selling Price (SP):</u>
- SP = MP - 18% = 0.82*1.2x = 0.984x
<u>Since the difference between CP and SP is Rs.20:</u>
- x - 0.984x = 20
- 0.016x = 20
- x= 20/0.016
- x = 1250
<u>Then:</u>
and
- SP = 1500*0.82 = Rs. 1230
Pay attention to the even numbers
