Answer:

d. 140.................

Answer 2

The value of missing number "option c) 130" is the required answer.

Step-by-step explanation:

We have,

1234 : 50 : : 4584 : 105 : : 7823 : 100 : : 6497 : ?

To find, the missing number = ?

The pattern follow:

Sum of the all digits × 5 = Given number

50 = (1 + 2 + 3 + 5) × 5 = 10 × 5 = 50

105 = (4 + 5 + 8 + 4) × 5 = 21 × 5 = 105

100 = (7 + 8 + 2 + 3) × 5 = 20 × 5 = 100

Similarly,

?  = (6 + 4 + 9 + 7) × 5 = 26 × 5 = 130

Hence, the value of missing number "option c) 130" is the required answer.
