I am a three digit number. I am an odd multiple of 50. The product of my first two digits is 45. What number am I ?

Is this homework ?

This is the homework given to my year four, 9 year old son to work out. Personally I think it is way too complex for them, although the teacher did say you may need an adult to help you think them through. I have worked them out but will ask my son to try for himself tomorrow. I just wanted to check that I had the correct answers (which i did ;) before tring to explain to him how to go about working yhem out.

I think it is too hard - and I don't get it's relevance to the primary curriculum (it's not number bonds or anything).

Cheeses.... these kids are going to be uber clever...

The only help they got was "remember the sum of means add" and "to find the product of two numbers you must multiply them" I may have a word with the teacher to find out the relevance of this homework as it is ridiculous for a 9 year old to be expected to do this

Homework is 'supposed' to be linked to the curriculum - I find a lot of it is just busy work (we are both ex-teachers so we find it really hard to make them do broccoli homework but obviously know that they have to do it - even though I don't personally agree with it!).

There isn't an odd multiple of 50 :), they are always even numbers. 950 is the answer /ignoring the "odd" part of the question/.
