1) people under 35 years of age are 3/4 of total member therefore people who are greater than or equal to 35 years of age are 1/4 of total member. but since we don't know the total no. of members hence 1 alone is not sufficient to answer the question.

2)64= 40/100 of total members; therefore total members=160; but since we don't know who many of these members are greater than or equal to 35 years of age hence 2 alone is not sufficient to answer the question.

combining 1 and 2 we have;

people greater than or equal to 35 years of age= 1/4*(total member)= 1/4*(160)=40;

hence answer should be C
O Excellence... my search for you is on... you can be far.. but not beyond my reach!
