Practice questions on Data Sufficiency - Weight — with answers

Try each question first, then open the answer. Explanations are included.

1. What is the weight of Anil? Statement I: The sum of Anil's and Sarita's weight is 893 kg. Statement II: The ratio of Sarita's weight to Gopal's weight is 8:7.

  1. AStatement I alone is sufficient to answer the question, while Statement II alone is not sufficient
  2. BStatement II alone is sufficient to answer the question, while Statement I alone is not sufficient
  3. CBoth statements together are sufficient to answer the question, but neither statement alone is sufficient
  4. DBoth statements together are not sufficient to answer the question
Show answer

Answer: D

Statement I gives only the combined total of Anil and Sarita (two unknowns, not sufficient alone). Statement II relates Sarita and Gopal, neither of which pins down Anil's weight on its own. Even combining both statements, Anil's weight cannot be uniquely determined, since the information about Gopal does not connect back to Anil. Hence both statements together are not sufficient.

2. What is the weight of Sanjay? Statement I: The sum of Sanjay's and Rekha's weight is 758 kg. Statement II: The ratio of Rekha's weight to Vikram's weight is 3:6.

  2. BStatement II alone is sufficient to answer the question, while Statement I alone is not sufficient
  3. CBoth statements together are sufficient to answer the question, but neither statement alone is sufficient
  4. DBoth statements together are not sufficient to answer the question
Show answer

Answer: D

Statement I gives only the combined total of Sanjay and Rekha (two unknowns, not sufficient alone). Statement II relates Rekha and Vikram, neither of which pins down Sanjay's weight on its own. Even combining both statements, Sanjay's weight cannot be uniquely determined, since the information about Vikram does not connect back to Sanjay. Hence both statements together are not sufficient.

3. What is the weight of Sanjay? Statement I: The sum of Sanjay's and Rekha's weight is 191 kg. Statement II: The ratio of Rekha's weight to Vikram's weight is 7:2.
