Answer: -20xy + 3y² + 3x²
Step-by-step explanation:
(xy + 2y² + 3y² - x²) - (12xy - 10y² - 18x² + 9xy + 12y² + 14x²)
(xy + 5y² - x²) - (21xy + 2y² - 4x²)
xy + 5y² - x² - 21xy - 2y² + 4x²
-20xy + 3y² + 3x²
Answer:
MP = RS 7,800
Step-by-step explanation:
Let
Marked price = MP
MP x (100 – 15) / 100 = Rs 6,630
MP × (85)/100 = Rs 6,630
MP = Rs 6,630 ÷ 85/100
MP = 6,630 × 100/85
MP = 663,000/85
MP = 7,800
MP = RS 7,800
