Solutions:
(1 – 2): Explanation:
Here mathematical
operation is followed in every step
Input:
15 11 18
14 16
06 19 13
Average of first and last
and second and second last number and so on taken and written.
Step1: (15 + 13)/2 =
14 (11 + 19)/2 = 15 (18 + 06)/2 = 12 (14 + 16)/2 =
15
First number is
multiplied with with difference with his next number
Step2: 14 × (15 – 14) =
14 15 × (15 – 12) = 45 12 × (15 – 12)
= 36
Second number is divided
by sum of digit of his previous number
Step3: 45/(1 + 4) = 45/5
= 9 36/(4 + 5) = 36/9 = 4
Difference between
numbers
Step4: 9 – 4 = 5
Now, for Input:
Product of numbers of
step 3 ⇒ 7 × 11 = 77
Difference = 77 – 53 = 24
As we can see 24 is
multiple of both 3 and 4 therefore this is correct option.
