2.Some cats are animals

3.No animal is cat

4.Some prouds are sheep

OPTIONS

1.Only 3 folllows

2.Either 2 or 3 follows

3.only  1 follows

4.only 3 and 4 follows

Answer 1

A) conclusions are missing in first question

B)

(wine (left))/(water (added))=343/169

It means = (wine (left))/(wine (initian amount))=343/512

 (∴ 343 + 169 = 512)

Thus, 343x = 512x(1-15/k)^3 ⇒343/512=(7/8)^3=(1-15/k)^3

⇒(1-15/k)=(7/8)

⇒ k = 120

Answer 2

(A) Option 2 is correct

(B) X=120 Liters

Comments

@ A_i_$_h See in the option it is given Either 2 or 3 follows

so when you draw diagram for the above statements you will realize that there are only two case either some cats are animals or no animals are cat.

@ankit but the diagram only confused me

it showed me some cats are animals

but i couldnt figure out "no animals are cats" from it

@A_i_$_h

That is one possibility only. In statement only mentioned that all cats are sheeps , so you can take cats

1. completely inside of sheeps and completely inside of animals

2. completely inside of sheeps and partially inside of animals

3.completely inside of sheeps and partially inside of proud and partially inside of animals

4. completely inside of sheeps and completely outside of animals

   Thus one of the conclusion 2 or 3 will definitely be correct. Either 2 or 3 (but both can't be true at a time you know)
