Correct Answer - Option 4 :
809 : 513
Adding the individual digit in the first number gives 8 and adding the individual digit in the second number gives 10 except 809 : 433
Let’s check each option.
1) 512 = 5 + 1 + 2 = 8 ; 613 = 6 + 1 + 3 = 10
2) 611 = 6 + 1 + 1 = 8 ; 901 = 9 + 0 + 1 = 10
3) 710 = 7 + 1 + 0 = 8; 433 = 4 + 3 + 3 = 10
4) 809 = 8 + 0 + 9 = 17 = 1 + 7 = 8; 513 = 5 + 1 + 3 = 9
Hence, “809 : 513” is the correct answer.
