2y = 5 × 8

2y = 40

y = 40/2

y = 20

x = 30/3

x = 10

Explanation

- All daffodils are plants.  

- All plants are living things.  

- Some living things are real.

Conclusion I: All daffodils are living things.  

✓ True, because daffodils → plants → living things.

Conclusion II: Some living things are flowers.  

✗ Not necessarily true. While daffodils are flowers and living things, the original statements do not mention flowers, so we can't assume this.

Conclusion III: All daffodils are real.  

✗ Not necessarily true. The statement only says some living things are real. 

Daffodils are living things, but that doesn't guarantee all daffodils are real.

Explanation

- I: Ibrahim looks after half of the trees in the orchard.  

- II: Ibrahim takes care of 300 trees.

If we know Ibrahim looks after half the trees (I) and that half equals 300 trees (II), then total trees = 300 × 2 = 600.

So:

- I alone is not enough (we don’t know total number).

- II alone is not enough (no info on total or fraction).

- Both I and II together are enough to find the total.

Explanation

Since P and Q are M’s parents, and Q is N’s mother, P must be the other parent of M.

So, P is M’s father (assuming traditional gender roles in this context).
