(A) 10011001 (I) 33
(B) 010.1010 . 1 (II) 44
(C) 100.100100 . 100 (III) 55
(D) 0.00100100 . 0010010 (IV) 66

Choose the correct answer from the options given below:

Options

  1. A(A)-(III), (B)-(IV), (C)-(II), (D)-(I)
  2. B(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
  3. C(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
  4. D(A)-(I), (B)-(II), (C)-(III), (D)-(IV)

Correct answer

C. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)

Step-by-step solution

Rules for significant figures:

1. All non-zero numbers are significant

2. Zeros between two non-zero digits are significant

3. Leading zeros are not significant

4. Trailing zeros to the right of the decimal are significant

5. Trailing zeros in a whole number with the decimal shown are significant

6. Trailing zeros in a whole number with no decimal shown are not significant

From above rule, we get

(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
