A. C + 6 < S − 2
B. C + 6 ≤ S + 2
C. C + 6 = S − 2
D. C + 6 > S − 2
E. C + 6 ≥ S − 2
C + 6 = Charles' age 6 years from now
S - 2 = Sarah's age 2 years ago
We're told that Charles' age (in 6 years) is AT LEAST AS BIG as Sarah's age (2 years ago)
In other words, Charles' age (in 6 years) is GREATER THAN OR EQUAL TO Sarah's age (2 years ago)
We can write: C + 6 ≥ S − 2
Answer: E

C. C + 6 = S − 2
D. C + 6 > S − 2
E. C + 6 ≥ S − 2
Now : C & S
After 6 Years : C + 6 = S - 2
AMong the given options and as per the highlighted part of the question stem only (E) follows, hence Answer must be (E)
