Question
A person "P" allocates 34% of their monthly income to
entertainment, 22% to food, 18% to studies, 12% to clothes, and the remainder to traveling. The difference between the amounts spent on entertainment and traveling is Rs. 3600. Determine the amount spent on food.Solution
ATQ,
Let monthly income of P is Rs. 100x Percentage of amount spent on travelling = 100 – 34 – 22 – 18 – 12 = 14% According to question 0.34 × 100x – 0.14 × 100x = 3600 34x – 14x = 3600 20x = 3600 x = 180 Monthly income of P= Rs. 18000 Money spent on food = 0.22 × 18000 = Rs.3960

I. 27(p + 2) = 2p(24 – p)
II. 2q2 – 25q + 78 = 0
I. 104x² + 9x - 35 = 0
II. 72y² - 85y + 25 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 32x + 252 = 0
Equation 2: y² - 30y + 221 = 0
If α, β are the roots of the equation x² – px + q = 0, then the value of α2+β2+2αβ isÂ
