Answer: Marked Prixe = Rs. 1800
Step-by-step explanation:
Let the marked price be M
1) A retailer allowed 12% discount and sold a T-shirt at a loss of Rs 16.
SP = 0.88M
CP - SP = 16
CP = 16 + SP
CP = 16 + 0.88M
2) If he had sold it at 10% discount he would have gained Rs 20.
SP = 0.9M
SP - CP = 20
0.9M = 20 + CP
CP = 0.9M - 20
16 + 0.88M = 0.9M - 20
0.9M - 0.88M = 20+16
0.02M = 36
36 = 0.02M
M = 1800
C
By subtracting 18 to both sides you are separating the 3x because you are not ready to isolate the variable (x) in step 1
The answer is D. The relative minimum and maximums are where they kind of curve and come back up or down. So that is 64 and -36.
True.
3 x 5 = 15
4 x 5 = 20
Therefore, 3:4 = 15:20
it is True
