Answer:
Question 1
<u>Given</u>
<u>Use formula and solve for x:</u>
- SP = CP + P
- 144 = x + (20% of x)
- 144 = x + 0.2x
- 144 = 1.2x
- x = 144/1.2
- x = 120
Cost price is N 120
Question 2
<u>Given</u>
- SP = 1000
- P = -20% (negative because of loss)
- CP = x
<u>Use formula and solve for x:</u>
- SP = CP + P
- 10000 = x - (20% of x)
- 10000 = x - 0.2x
- 10000 = 0.8x
- x = 10000/0.8
- x = 12500
Cost is N 12500
