Worked practice questions

In a GMAT DS question, what is the FIRST step?

  1. Test both statements together immediately
  2. Compute the actual numeric answer to the question
  3. Test Statement 1 alone for sufficiency
  4. Pick (C) by default
Show answer and solution

Correct answer: C. Test Statement 1 alone for sufficiency

Always evaluate each statement alone first, before combining. Skipping to both-together wastes time when one alone might be sufficient (which would give A, B, or D).

Is 1,287 divisible by 3?

  1. No, since 1+2+8+7 = 18 not divisible by 3
  2. Yes, since 1+2+8+7 = 18 is divisible by 3
  3. No, since 1287 is a prime number
  4. Yes, since 1287 ends in 7
Show answer and solution

Correct answer: B. Yes, since 1+2+8+7 = 18 is divisible by 3

Divisibility rule for 3: sum of digits = 1+2+8+7 = 18, which IS divisible by 3. So 1287 is divisible by 3 (1287 = 429 × 3).

On a percentage question with abstract values, the recommended smart-number to assume is:

  1. Always use 1 as the base
  2. Use 100 for cleaner arithmetic
  3. Always use 60 as the base
  4. Use 1000 in all problems
Show answer and solution

Correct answer: B. Use 100 for cleaner arithmetic

100 is the GMAT-standard smart number for percentage problems. It makes percentages map directly to absolute values (30% of 100 = 30).
