An easier maths puzzle to solve

7 ÷ 7 = 1
7 x 7 = 49

7 + 1 = 8
8 + 49 = 57

57 - 7 = 50

Bump!

I didn't get a pm so obviously got it wrong.

Hope all is well with you Marydoll

You got it right, Callistemon? You and I are not meant to receive PMS from each other!

The answer is indeed 50. So well done all.

I've run out of apples, so jusqu'à demain! That's your french lesson for today!

The correct answer is 50 and the explanation is posted above.

Where did the one I was doing go?!

Ah...I was still on page 1 !! It's not that I was slow at working out. ?

Juliet that is indeed answer is 43. ?

Triangles - Inside number is obtained by multiplying the three numbers shown on the outside

3rd triangle.....multiply the numbers shown 6,3,7 (in any order) = 126

Mary's age.....Leap year happens every four years with some exceptions. According to several calendars I consulted, 1896 was a leap year, as were 1892, 1896 and 1904. (1895 was not and neither was 1900). Born in 1895, Mary's birthday would have marked the passing of 122 (regular years) some time in 2017. Divided by 4, that would have been 30.5 years.....but 1895 was not a leap year.....so where does that leave us?

Oops...I almost didn't see the one about the children!

Let's see....

Miss Brown (3 years older) is 10 and Mary is 7. Surname White is the 9 year old boy. Mary can't be Miss Brown or Master White therefore she's Mary Green. First names are Ann, Brian and Mary....she's not Brian or Mary, so that leaves us only with Miss Ann Brown.

Ann Brown 10
Brian White 9
Mary Green 7

Nice brain teasers! Thanks

Marydoll posted the answer to the Mary's age question upthread

She was teasing us!

Merci beaucoup, Mariepoupée

I would share the ? with you Whitewave but not just at the moment, sorry!

Mea culpa, mea maxima culpa! ?

7+ (7/7) + (7x7) -7
7 + (1+49) -7
7 + 50 -7
57 - 7 = 50

willa, well done, but the answer has already been posted upthread! .
I have run out of red apples, so you will have to settle for ?

A new puzzle tomorrow!

Wednesday's puzzle. I'll leave it until lunchtime and come back with the answer.
There is more than one solution

Thank you

Just about to get up will tackle it after my cups of tea, feeding the birds, reading the paper, breakfast, ironing, housework and my daily workout?

Life is all go isn’t it?

Bump

Sat with breakfast

Just started - I will get back in a fortnight or so?

Does bodmas come into this?

I know it doesn’t really? I only said that because I don’t know how to bump.

Still haven’t had time to look at it though.

Just about to do my daily work out, pick in some washing then have a shower. I have soup to make as well.

No BODMAS, just problem solving. ?

8 1 6
3 5 7
4 9 2

= 15

That's one solution. ?

4 3 8
9 5 1
2 7 6

Just noticed mine is Calli's turned sideways, I spent too long trying to make a box grid, and failed
