Question

Let a, b, c, d and e be integers such that a = 12b = 24c, and 4b = 15d = 24e. Which of the following pairs contains a number that is not an integer?
(A) (a/18 , b/e)
(B) (b/c , a/de)
(C) (b/6 , cd/e)
(D) (a/4b , d/e) ​

Answer 1

Answer:

D is the correct answer

Step-by-step explanation:

15d=24e

So, d/e=24/15

d/e=1.6

and as we know 1.6 is not an integer
