Khurram is the answer 81

this is how i solved
9 odd so = 27
6 even so 6/2 = 3

fn 9 * fn 6 = 27 * 3 = 81

Answer is D


Yes the answer is 81, but you need to look at the answer choices, they are in a "BOX", meaning the answer choices follow the same rule as presented in the stem.

Using the rule for ODD integers, 27 * 3 = 81, so pick D. (Answer choice A actually represents the number 243)

Hope that helps.

guys yaa my mistake.....answe is indeed D

Khurram seee the issue is even the answer is in a box its no plain 27 but a boxed 27 ...


so as 27 is odd then it will be 3 * 27 = 81

hence answe is D
