Question
Liquid 'X' is made up of milk and water in the ratio
3:2, and liquid 'Y' has milk and water in the ratio 5:4. If 50 ml of 'X' is combined with 36 ml of 'Y', how much milk is there in the resulting mixture?Solution
ATQ,
Quantity of milk in 50 ml of 'X' = 50 × (3/5) = 30 ml
Quantity of milk in 36 ml of 'Y' = 36 × (5/9) = 20 ml
So, quantity of milk in final mixture = 30 + 20 = 50 ml
I. 3x2 - 14x + 15 = 0
II. 15y2 - 34 y + 15 = 0
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...
Equation 1: x² - 144x + 5184 = 0
Equation 2: y² - 130y + 4225 = 0
Let 's' represent the sum of the highest root of equations I and III, and 'r' denote the product of the lowest root of equation I and the highest root o...
I. p2 – 15p + 56 = 0
II. q2 + 2q – 63 = 0
I. 2y2 - 15y + 18 = 0
II. 2x2 + 9x - 18 = 0
I. x2 + (9x/2) + (7/2) = - (3/2)
II. y2 + 16y + 63 = 0
I. 165x² + 97x + 10 = 0
II. 117y² - 163y + 56 = 0
- Suppose both the roots of q² + kq + 49 = 0 are real and equal, then determine the value of 'k'.
I.√(3x-17)+ x=15
II. y+ 135/y=24
