Answer:
15%
Step-by-step explanation:
Let
Selling price = SP
Cost price = CP
If CP = 100
Profit = selling price - cost price
x% = SP - x% of 100
x% + 100x% = SP
SP = 100 (1 + x/100) (1)
If CP = 92
SP = 92 (1+ {x+10}/100)
Equate both SP
100 (1 + x/100) = 92 (1+ {x+10}/100)
100 + x = 92 + [{23/25} * (x+10)]
{2/25}x = 30/25
x = 30/25 ÷ 2/25
= 30/25 × 25/2
= 30/2
x = 15%
Answer:
I got 2,717.45
Step-by-step explanation:
I did 2,363 × 15% = 354.45
then 2,363 + 354.45 = 2,717.45
Step-by-step explanation:
The answer is A. (x - 4)(x - 12).
