Answer 1

1. 923

2. 3

3. yes

4. no

5. a= 2, b= 3

6. A, B, C are digits.

7AB = 700+ 10 A + B. Its value is between 700 and 799.

CC = 10 C + C = 11 C, C * CC = 11*C²

Given 700+ 10 A + B = 11 C²

So 700 <= 11 C² <= 799

63 <= C² <= 72

Hence, C = 8.

So 11 C² = 11 * 8² = 704

Hence, B = 4, A = 0.

A =0, B = 4, C = 8

7. b= 4 c= 3 a= 5

8. 2 yes, 9 yes, 10 no

9 a) 321 , b) 247
