Here are the answers to Sunday's brain teasers
Question one
1. Martin is 33 years old today which is three times as old as his brother Henry was when he, Martin, was the age his brother Henry is today. How old is Henry?
Answer...
Take the present age of Henry to be Y. Thus, Martin was Y years old when Henry was 11 years old (Martin is three times as old as his brother Henry was when he, Martin, was the age his brother Henry is today). Do you catch the drift?
Therefore:
Martin :/ Henry
33 YEARS :/ Y YEARS
Y YEARS :/ 11 YEARS
What is Y?
Martin's present age (33 years) = Y + 11
33 = Y + 11
33-11 = Y
22 = Y
Henry is 22 years old.
Question two
2.It's Tuesday and I say: "I'll be back three days before one week after the day after tomorrow." When shall I be back?
Answer...
If it is Tuesday, then we start counting one week the day after tomorrow, that is Thursday. So it goes, I'll be back three days before next Thursday. This will be Tuesday. So I'll be back on Tuesday.
Question three
3. Twelve mangoes are hanging high up. Twelve men pass and each takes a mango. Eleven mangoes are left hanging. How can this be?
Answer...
There are 12 mangoes. Each takes a mango and 11 remain. So it apparently appears that Each is the name of a person. (Sorry I didn't capitalize the 'E' in each (in the question)).
Question four
4. A man stands looking at the picture of a man and says: "Sisters and brothers have I none, but this man's father is my father's son." Whose picture is he looking at?
Answer...
This man has neither brothers nor sisters. So who is the man's father's son? It is HE! Thus, if the father of the man in the picture is the man's (man looking at picture) father's son and HE is his father's son, he is looking at his son's picture!!!!
....... I hope you had a good time with them.
