Question

A, b, c, d and e are five consecutive integers and the average of these five numbers is less than 1/4th of



a. then a is select one:



a. data sufficient



b. even



c. positive



d. negative

Answer 1

1stly, it is given that a, b, c, d and e are 5 consecutive integers. So,

b=a+1, c= a+2, d=a+3, e=a+4

2ndly, it is given that

(a+b+c+d+e)/5<a/4

=>{a+a+1+a+2+a+3+a+4)/5<a/4

=>4(5a+10)<5a

=>20a+40<5a

=>20a-5a<-40

=>15a<-40

=>a<-40/15

As a is less than a negative number, so 'a' is also a negative number.

(d) is correct answer.
