Question:

Match the List I with List II

List I List II
A. 5x + 2 = 0 I. 5/4
B. -2x + \(\frac{5}{2}\) = 0 II. 1/4
C. x + 7 =6 III. -2/5
D. -2x + \(\frac{3}{2}\) = 1 IV. -1

Choose the correct answer  from the options given below:

Options:

A-III, B-I, C-IV, D-II

A-III, B-IV, C-II, D-I

A-II, B-III, C-I, D-IV

A-II, B-IV, C-III, D-I

Correct Answer:

A-III, B-I, C-IV, D-II

Explanation:

A ⇒  5x + 2 = 0

       x = -2/5   .......(III)

B ⇒ -2x + \(\frac{5}{2}\) = 0

       -2x = - \(\frac{5}{2}\)

         x  =  \(\frac{5}{4}\)   .........(I)

C ⇒ x + 7 =6

       x = 6 - 7 = -1    ........(IV)

D ⇒ -2x + \(\frac{3}{2}\) = 1

       -2x = 1 - \(\frac{3}{2}\)

       -2x =  - \(\frac{1}{2}\)

          x = - \(\frac{1}{4}\)    .........(II)

Therefore, correct answer is

A-III, B-I, C-IV, D-II
