L is the mother of M. M is the mother of O. O is the sister of H. H is the wife of P. P is the father of F. F is the mother of G. How is M related to F?
Mother’s mother
In blood-relation puzzles the safest method is to convert each sentence into a small family tree, keeping generations aligned. Let us build it step by step from the clues:
- L is the mother of M → L is one generation above M.
- M is the mother of O → M is above O; so O is L's grandchild.
- O is the sister of H → H is on the same level as O, so H is also a child of M.
- H is the wife of P → P marries into M's family at H's level.
- P is the father of F → since H is P's wife, H is the mother of F; F is one generation below H (and below M).
- F is the mother of G → F is above G (this clue is extra and does not affect M–F).
Now trace the line from M down to F: M is the mother of H, and H is the mother of F. Therefore M is F's grandmother — specifically F's mother's mother (F's mother is H, and H's mother is M).
Note the gender is fixed here: M is female (she is described as a mother), so "grandmother" is exactly right. The distractors fail because M is not on F's own generation (ruling out mother's sister / father's sister), and M is two generations above F, not below (ruling out sister's daughter). Hence the correct answer is Mother's mother.
