Question

A: If 2+4 =7, then 3+4=8
B: if 3+5 =8,then earth is flat.
C: if A and B are true, then 5+4 = 11

Tell which of these are false and which are true with explanation . ​

Answer 1

Step-by-step explanation:

b is true and a and c is false

Answer 2

This is a mathematical reasoning question.

Reasoning questions generally have two interdependent statements in a statement.

Those two statements follows:

T + T = T

F + F = T

F + T = T

T + F = F

In A,

We have 2+4 = 7, [false] and 3 + 4= 8 [false] .

Both are false, so this statement is True.

In B,

We have 3+5= 8, [true] and earth is not flat as we all know [false]

So this statement is False.

In C,

We have a condition, if A and B are true (but they both aren't true[false] ), and 5+4=11 [false]

So this statement is True

So, B is false, A and C are true.

Lol, sorry, I answered my own question.

I love you btw. : )
