Question
A and B started a business with initial investments of
Rs. 28000 and Rs. 30000 respectively. After one year, a profit of Rs. 5800 is earned. A being a working partner gets 30% of the profit for managing the business and rest of the profit is shared between them in the ratio of their investments. A invested his whole profit in a scheme offering 10% compound interest compounded annually. Find the interest earned by A after 2 years.Solution
The ratio of their investments = 28000:30000 = 14:15 Profit share of A for being a working partner = 0.30 times; 5800= Rs. 1740 Profit share of A for his investment = 14/29 times; 0.70 times; 5800 = Rs. 1960 Total profit of A = Rs. 1960 Compound interest earned by A = 3700{(1 + 0.10)2ndash; 1} = Rs. 777
I. x2 – 39x + 360 = 0
II. y2 – 36y + 315 = 0
I. 40 x² - 93 x + 54 = 0
II. 30 y² - 61 y + 30 = 0
What will be the product of smaller roots of both equations.
I. 3x2 - 14x + 15 = 0
II. 15y2 - 34 y + 15 = 0
I. x2 – 13x + 36 = 0
II. 3y2 – 29y + 18 = 0
Equation 1: 2x2 - 21x + 54 = 0
Equation 2: 4y2 - 23y + 15 = 0
Difference between the roots of equation 1 is approx...
I. 4x² - 15x + 9 = 0
II. 20y² - 23y + 6 = 0
- For what value of a does the quadratic equation x² + ax + 81 = 0 have real and identical roots?
In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answer
I. x² - 8x + 15 = 0 ...
I. 3x2 + 3x - 60 = 0
II. 2y2 - 7y + 5 = 0
