Question

In the given equations, the function ⇒ remains unchanged. What will come in place of the question mark (?) in the fourth equation?

1) 5 ⇒ 3 = 19

2) 6 ⇒ 3 = 22

3) 6 ⇒ 5 = 34

4) 12 ⇒ 2 = ? 

1. 29
2. 30
3. 28
4. 16

Answer 1

Correct Answer - Option 3 : 28

The given set of equations:

1) 5 ⇒ 3 = 19

2) 6 ⇒ 3 = 22

3) 6 ⇒ 5 = 34

4) 12 ⇒ 2 = ? 

In equation 1),

5 × 3 + 4 = 19

In equation 2),

6 × 3 + 4 = 22

In eqaution 3),

6 × 5 + 4 = 34

SImilarly, in equation 4),

12 × 2 + 4 = 28

Hence, 28 is the correct answer.
