To find the profit percentage:

Cost Price (CP) = 560

Selling Price (SP) = 600

Profit = SP - CP

= (40 / 560) * 100

= 7.14%

Explanation

Let's factorize 2x^2 - 7x + 3. We need to find two numbers that multiply to 2 × 3 = 6 and add to -7. These numbers are -6 and -1.

So, 2x^2 - 7x + 3 = 2x^2 - 6x - x + 3

= 2x(x - 3) - 1(x - 3)

= (2x - 1)(x - 3)

Explanation

Rauf's monthly income is Rs. 7200, and the pie graph shows his expenditure on education as 70°. To find the amount spent on education, we calculate the fraction of his income spent on education.

The fraction of income spent on education is 70° out of 360° (total degrees in a circle).

Fraction = 70° / 360° = 7/36

Amount spent on education = (7/36) × 7200 = 7 × 200 = 1400
