Question
Rahul spends 80% of his salary and earns an allowance of
5% of his salary each month. His annual saving is Rs. 94500. Find his monthly allowance. [Monthly income = salary + allowance]Solution
ATQ,
Let salary = ₹x Spends = 80% of x → Saving from salary = 20% of x = 0.20x Allowance = 5% of x = 0.05x Monthly saving = 0.20x + 0.05x = 0.25x Annual saving = ₹94,500 →12×0.25x = 94500 ⇒3x = 94500 ⇒ x = 31500 Monthly allowance = 5% of 31500 = ₹1575
I. 2y² - 35y + 132 = 0
II. 2x² - 31x + 110 = 0
I. x² - (16)2 = 0
II. 2y - 14 = 0
I. x2 – 18x + 81 = 0
II. y2 – 3y - 28 = 0
I. 81x - 117√x + 40 = 0
II. 81y - 225√y + 136 = 0
I. x2 – 12x + 32 = 0
II. y2 + y - 20 = 0
I. 2 x ² + x  – 1 = 0                Â
II. 2 y ² - 3 y + 1 = 0
...- What should be the value of t in the equation x² + tx + 64 = 0 so that it has two equal real roots?
How many values of x and y satisfy the equation 2x + 4y = 8 & 3x + 6y = 10.
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between 'p' and 'q' and choose...
l). p² - 26p + 153 = 0
ll). q² - 17q + 72 = 0
