Directions: Study the following numbers carefully and answer the questions given beside:
867 495 736 592 619
If 1 is subtracted from each odd digit of each of the numbers first and then each perfect square digit is changed into 5, what is the sum of the least and the greatest number in the sequence thus obtained?
Options
- A1346
- B1398
- C1338
- D1448
Correct answer
D. 1448
Step-by-step solution
The given sequence:
867 495 736 592 619
Subtracting 1 from each even digit of each of the numbers:
866& & & 484& & & 626& & & 482& & & 608&
Changing every perfect square digit into 5, we get:
866& & & 585& & & 626& & & 582& & & 608&
The sum of the least and the greatest number:
582 + 866 = 1448
Hence, the correct answer is option D.
