Question 46

In some code, letters a, b, c, d and e represent numbers 2, 4, 5, 6 and 10. We just do not know which letter represents which number. Consider the following relationships:

I. a + c = e,
II. b - d = d and
III. e + a = b

Which of the following statements is true?

Solution

Share

We have a +c=e so possible summation 6+4=10 or 4+2 = 6.
Also b=2d so possible values  4=2*2 or 10=5*2.
So considering both we have b=10 , d=5, a=4 ,c=2, e=6.
Hence the correct option is B .
