For the four sets of three measured physical quantities as given below. Which of the following options is correct? (i) A = 24.36, B = 0.0724, C = 256.2 (ii) A = 24.44, B = 16.082, C = 240.2 (iii) A = 25.2, B = 19.2812, C = 236.183 (iv) A = 25, B = 236.191, C = 19.5 (1) A + B + C < A + B + C = A + B + C = A + B + C (2) A + B + C = A + B + C = A + B + C = A + B + C (3) A + B + C = A + B + C = A + B + C = A + B + C (4) A + B + C < A + B + C < A + B + C < A + B + C

1. (1) A + B + C < A + B + C = A + B + C = A + B + C
2. (2) A + B + C = A + B + C = A + B + C = A + B + C
3. (3) A + B + C = A + B + C = A + B + C = A + B + C
4. (4) A + B + C < A + B + C < A + B + C < A + B + C

Correct answer: (1) A + B + C < A + B + C = A + B + C = A + B + C

Solution

The correct option indicates that the sum of the quantities in the first set is less than the sum of the quantities in the second set, while the sums of the remaining sets are equal, reflecting the differences in the values of A, B, and C across the sets.
