Answer 2

1) (a)

2) (c)

3) (b)

4) (d)

5) (b)

Explanation:

According to the given information, the letters A, B, C, D, E, F and G, not necessarily in any order, stand for the digits 1 to 7.

Now, according to the given information, it is given that, B is the middle term. Now, since 4 is the middle number among, 1, 2, 3, 4, 5, 6 and 7,

B corresponds t the number 4.

Now, D is 4 less than A and A and B are consecutive digits. This clearly means that A is after B and D is the first letter, that is the letter corresponding to 1. This is because if A would be before B, D would not have a place 4 steps away from B.

Also, it is given that, E and C lie between B and D. Thus, E and C corresponds to the numbers 2 and 3 respectively. Again, it is given that, G is greater than F, which makes F correspond to 6 and G correspond to 7.

Thus, the arrangement becomes,

1  2  3 4 5 6 7

D E C B A F G

Then, 5 is (a) A.

Also, since B = 4 and D = 1, then, B - D = 4-1 = 3 which is option c.

Also, C = 3, E = 2, then C+E = 5, that is option b.

Also, the digit between A and G is F, that is option d.

The exact values of C and E are not known and might have their places reversed. Thus, option b is correct.

Hence, the answers are,

1) (a)

2) (c)

3) (b)

4) (d)

5) (b)
