#everydayquiz #10Questions
Directions (Q. 1–4): In each of these questions, two equations numbered I and II with variables x and y are given. You have to solve both the equations to find the value of x and y. Give answer
1) if x > y
2) if x >= y
3) if x < y
4) if x <= y
1.
I. x^2 + x – 20 = 0
II. y^2 + 13y + 40 = 0
2.
I. x^2 – 11x + 30 = 0
II. y^2 – 13y + 40 = 0
3.
I. x^2 + 10x + 25 = 0
II. 5y^2 – 2 15 y + 9 = 0
4.
I. 10x^2 – 29x – 21 = 0
II. y^2 + 13y – 68 = 0

3) 408
4) 416
5) 424
Directions (Q. 8–10): What value should come in the place of question mark (?) in the following questions?
8. 168.781 – 112.412 – 8.409 – 1.150 = ?
1) 44.81
2) 46.81
3) 40.81
4) 47.81
5) 46.61
9. [(3√27) + 2√27) * (27√27 + 26√27)] – 159√27 = ?
1) 1431
2) 1331
3) 1421
4) 1441
5) 1231
10. 8.5% of 160 – 0.42% of 750 = ?
1) 11.45
2) 12.45
3) 13.45
4) 9.45
5) 10.45
1.2
I. x^2 + 5x – 4x – 20 = 0
(x – 4) (x + 5) = 0
x = 4, – 5
II. y^2 + 8y + 5y + 40 = 0
(y + 8) (y + 5) = 0
y = –8, – 5
x >= y
2.5
I. x^2 – 6x – 5x + 30 = 0
(x – 5) (x – 6) = 0
x = 5, 6
II. y^2 – 8y – 5y + 40 = 0
(y – 8) (y – 5) = 0
y = 8, 5
No relationship between ‘x’ and ‘y’ exits.
3. 3;
I. (x + 5)^2 = 0
x = –5
II. (√5y – √3)^2 = 0
x = √3/√5
4. 5
I. 10x^2 – 35x + 6x – 21 = 0
(5x + 3) (2x – 7) = 0
x = -3/5, 7/2
II. y^2 + 17y – 4y – 68 = 0
(y – 4) (y + 17) = 0
y = 4, –17
No relationship between x and y exists.
5. 1;
6. 4
7. 3
8. 2
? = 46.81
9. 1
? = (3 + √27)(53√27) - 159√27
= 159√27 + 53 * 27 - 159√27 = 1431
10. 5
? = 8.5/100 * 160 - 0.42/100 * 750
= 13.6 - 3.15 = 10.45
