Question 26

The total weight is 6.35 kg.

To find the total weight, we first convert all weights to the same unit, kilograms. The weights in kilograms are 1.2 kg, 0.4 kg (for 400 g), 3.5 kg (for 3 1/2 kg), and 1.25 kg (for 1 1/4 kg). Adding these together gives 1.2 + 0.4 + 3.5 + 1.25 = 6.35 kg.

A) 6.35 kg

This option is correct because the total weight calculated from the individual weights is indeed 6.35 kg. Each weight has been accurately converted and summed.

B) 6.40 kg

This option is incorrect as it does not reflect the accurate summation of the weights provided. The individual weights add up to 6.35 kg, making 6.40 kg an incorrect total.

C) 6.45 kg

This option is also incorrect. The total weight calculated is 6.35 kg, and 6.45 kg exceeds this total, indicating a miscalculation.

D) 6.30 kg

This option is incorrect as well. The total of the weights is 6.35 kg, and 6.30 kg is lower than the correct sum, demonstrating an error in addition.

Conclusion

The correct answer is 6.35 kg because it is the precise sum of all the individual weights converted to kilograms. All other options fail to accurately represent the total weight, either by being too high or too low. Thus, A is the definitive and correct choice based on the calculations.
