Answer 1

Correct Answer - Option 2 : 19

Given

19	9	140
17	9	130
?	5	120

 

The logic follows here is :-

19 , 9 , 140

(19 + 9) × 5

28 × 5 = 140,

17, 9, 130

(17 + 9) × 5

26 × 5 = 130,

Similarly,

? , 5 , 120

(? + 5) × 5 = 120

(? + 5) = 120 ÷ 5

(? + 5) = 24

? = 24 - 5

? = 19

Hence, the correct answer is 19.
