Of the 1,000 companies responding to a certain survey, what percent indicated that they had a business recovery plan?

(1) 200 of the companies did not indicate that they had a business recovery plan. This implies that the remaining 800, or 80%, indicated that they had a plan. Sufficient.

(2) The number of companies that indicated that they had a business recovery plan was 4 times the number that did not indicate that they had a business recovery plan. {Indicated} + {Indicated}/4 = 1,000 --> {Indicated} = 800, or 80%. Sufficient.

Hope it's clear.

Bunuel,

My question is that in Statement 1, no where its mentioned that remaining 80% had a plan. Is it right to assume in DS questions?

Bunuel,

Actually no such assumption was made, it's a fact.

There are only two answers to the question "do you have a plan?":
YES.
NO.

If NO=800, then YES=1000-800=200. How else?

As it is a DS question, i think, it would be much clear had the question mentioned that " All respondents have answered the question". Question is binary so "yes or no answer can be assumed"

I think we can assume that all have responded as the question states "Of the 1,000 companies responding to a certain survey"

This is a data sufficiency question. Options for DS questions are always the same.

The data sufficiency problem consists of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements, plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of the word counterclockwise), you must indicate whether—

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
C. BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
E. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

I suggest you to go through the following post ALL YOU NEED FOR QUANT.

Hope this helps.

Not sure I understand what you mean.

There are only two answers to the question "do you have a plan?":
YES.
NO.

If NO=800, then YES=1000-800=200. How else?

A typical survey will have 1 or more questions. The surveyee may choose not to reply to a survey question that is not mandatory.

When surveyee does not respond to the question then the case is "did not indicate that they had a business recovery plan"
When surveyee responds "No" to the question then the case is "indicated that they did not have a business recovery plan"

I do not intend to contest your solution since I see where you're coming from. But, DS questions do test for unsupported assumptions. Assumption that survey question was mandatory or every participant responded to the survey question, is not supported in the question stem. That is how I read the question. Maybe I'm wrong - at least by the rule that question-maker's answer is always right!

1- 200 no recovery plan-> 800 / 1000 = % of companies that had a bp recovery
2- recovery = 4(norecovery)
recovery + norecovery = 1000
you can set up system two equations and two unknowns
