583 : 488 :: 293 : ?
Option 1: 378
Option 2: 487
Option 3: 581
Option 4: 291
Correct Answer: 378
Solution : Given:
583 : 488 :: 293 : ?
Like, 5 + 8 + 3 = 16; 4 + 8 + 8 = 20; 20 – 16 = 4.
Similarly, 2 + 9 + 3 = 14; The sum of the digits of the missing number will be 18.
Let's check the options —
First option: 378; 3 + 7 + 8 = 18. The sum of the digits is 18.
Second option: 487; 4 + 8 + 7 = 19. The sum of the digits is not 18.
Third option: 581; 5 + 8 + 1 = 14. The sum of the digits is not 18.
Fourth option: 291; 2 + 9 + 1 = 12. The sum of the digits is not 18.
Hence, the first option is correct.
