Question Details

Directions: In each of the following questions, two equations numbered I and II are given. You have to solve both equations and mark the appropriate option.

I. x 2 12 x + 35 = 0 II. y 2 + 7 y + 10 = 0

Options

A

If x = y or no relation can be established between x and y

B

If x ≥ y

C

If x ≤ y

D

If x > y

E

If x < y

Show Answer

Correct Answer :

Option D

If x > y

Solution :

The correct answer is If x > y.

Step 1: Solve Equation I for x

x2-12x+35=0

Factorize the quadratic equation by splitting the middle term:

x2-7x-5x+35=0

x(x-7)-5(x-7)=0

(x-5)(x-7)=0

This gives the roots for x:

x=5 or x=7

Step 2: Solve Equation II for y

y2+7y+10=0

Factorize the quadratic equation by splitting the middle term:

y2+5y+2y+10=0

y(y+5)+2(y+5)=0

(y+2)(y+5)=0

This gives the roots for y:

y=-2 or y=-5

Step 3: Compare the values of x and y

Comparing each calculated value of x with each value of y:

For x=5: 5>-2 and 5>-5 (so x>y)

For x=7: 7>-2 and 7>-5 (so x>y)

In all cases, every value of x is strictly greater than every value of y.

Therefore, the relationship is If x > y.
