5th and 6th class boys have been using their logic to try solve some tricky problems given by Mr. Smyth. It wasn’t easy but some boys managed to work them out. Have a look at Monday’s and Tuesday’s problems. Can you solve them??



A census taker approaches a house and asks the woman who answers the door How many children do you have, and what are their ages?” 

The woman replies I have three children, the product of their ages are 36, the sum of their ages are equal to the address of the house next door. 

The census taker walks next door, comes back and says I need more information. 

The woman replies “I have to go, my oldest child is sleeping upstairs.” 

Census taker then says “Thank you, I now have everything I need.” 



A man has to get a fox, a chicken, and a sack of corn across a river. 

He has a rowboat, and it can only carry him and one other thing. 

If the fox and the chicken are left together, the fox will eat the chicken. 

If the chicken and the corn are left together, the chicken will eat the corn. 

How does the man do it?
