Detailed Solution
Download Solution PDFThe pattern followed here is,
Sum of digits of 1st number + 1 = Sum of digits of 2nd number.
Now follow the steps:
223 : 350
Sum of digits of 1st number + 1 = Sum of digits of 2nd number.
=> = (2 + 2 + 3) + 1 = 3 + 5 + 0
=> 7 + 1 = 8
=> 8 = 8
Similarly,
519:?
=> Sum of digits of 1st number + 1 = (5 + 1 + 9) + 1 = 15 + 1 = 16
Check option all options:
Option (1): 736 → 7 + 3 + 6 = 16
Option (2): 687 → 6 + 8 + 7 = 21
Option (3): 654 → 6 + 5 + 4 = 15
Option (4): 645 → 6 + 4 + 5 = 15
Hence, "736" is correct answer.
Alternate Method
223 : 350
⇒ 63 + 7= 216 + 7 = 223; 73 + 7 = 343 + 7 = 350;
