In what year was Edward born?
(1) In 1988, Edward turned 17 years old.
(2) Edward’s sister Lisa, who is 14 months older than Edward, was born in 1970
Let's first look at both the statements individually, and then, if required, we can try checking using both together:
Statement 1: In 1988, Edward turned 17 years old.
Since Edward turned 17 years old in the year 1988, his year of birth would be 1988-17 = 1971
Hence, we can uniquely determine his year of birth using Statement 1 alone.
Now, let's look at Statement 2:
Statement 2: Edward’s sister Lisa, who is 14 months older than Edward, was born in 1970
This can be a trap if you don’t pay close attention to the exact condition stated.
Given: Edward’s sister Lisa, who is 14 months older than Edward, was born in 1970
Basically, Lisa is 1 year and 2 months older than Edward. Now, here, the exact month in which Lisa was born also matters because it will change the year of birth of Edward accordingly.
Case 1 - Lisa born in December 1970
In this case, the year of birth of Edward becomes 1972 (Edward born in February 1972)
Case 2 - Lisa born in January 1970
In this case, the year of birth of Edward becomes 1971 (Edward born in March 1971)
More generally, for Edward to be born in 1971, Lisa must be born between Jan 1970 and Oct 1970 (inclusive); for Edward to be born in 1972, Lisa must be born late enough in 1970 - in November or in December.
Hence, we cannot determine the year of birth of Edward uniquely using Statement 2 alone.
Therefore, the correct answer should be Option A - Statement 1 sufficient, 2 insufficient
