CAT 1997 — QA Question 27
Number TheoryEasy
P, Q and R are three consecutive odd numbers in ascending order. If the value of three times P is 3 less than two times R, find the value of R.
Answer & solution
Correct answer: 9
- A
5
- B
7
9
- D
11
Solution
As P, Q and R are consecutive odd numbers, Q = P + 2 and R = P + 4. Now 3P = 2(P + 4) – 3. On solving this equation, we get P = 5.
Therefore, R = 5 + 4 = 9
