(D) 603

(E) 568

 

Answer 1. (D)

Solution:

Ascending order: 197 458 620 831 937

Second smallest number = 548

Third digit of the second smallest number = 8

Third highest number = 620

First digit of the third highest number = 6

According to the question,

= 8 × 3 + 6 × 3

= 24 + 18 = 42

 

Answer 2. (E)

Solution:

After arranging each digit of the five numbers in descending order,

831 971 854 620 973

Second highest number = 971

Sum of the digits = 9 + 7 + 1 = 17

 

Answer 3. (B)

 

Answer 4. (B)

Solution:

Ascending order = 197 458 620 831 937

Fourth highest number = 458

Fourth smallest number = 831

According to the question,

= (4 + 8) × (3 + 1)

= 12 × 4 = 48

 

Answer 5. (A)

Solution:

After arranging each digit of the five numbers in ascending order,

138 179 458 026 379

Highest number = 458

Smallest number = 026

Difference = 458 – 026 = 432
