In the figure shown, b = ?

(1) All the marks are equally spaced
(2) a = — 1

EG

1) if all the marks are equally spaced

Let the increments be in 1
if a = 0 then b = 1
If a = 1 then b = 2

Insufficient.

2)

a = -1 we don’t know about the spacing and we cannot tell if be will be 0 or 1 etc..

Combined.

if the increments in 1

Then b = 0

if the increments in 2

Then b = 1

Insufficient

+1 for E

Neither individually nor using both the statements we can reach an answer.

In the figure shown, b = ?

(1) All the marks are equally spaced
(2) a = — 1

EG

Target question: What is the value of b?
Go straight to.....

Statements 1 and 2 combined
There are several scenarios that satisfy BOTH statements. Here are two:
Case a: a = -1, b = 0, c = 1 and d = 2. In this case, the answer to the target question is b = 0
Case b:a = -1, b = 1, c = 3 and d = 5. In this case, the answer to the target question is b = 1
Since we cannot answer the target question with certainty, the combined statements are NOT SUFFICIENT

Cheers,
Brent
