Dear Friends,
Laetitia is a lovely lady chef at Musica Mundi School whose birthday is coming up on 28 May in just two days from now. Brilliant Benjamin is a student who’s had a great school year as a 16-year-old, and we’ll have special puzzles to celebrate him turning 17 this coming Wednesday 29th. I’m hoping for more solvers like Super Seinel who submitted the best answers to the most recent puzzles that I shared at the school. She will be receiving a very nice prize pen tomorrow. ππ
A Starter Puzzle in Honour of Laetitia’s Birthday on 28 May π
Use the numbers 2, 8, 2, 8, 2 in any order you like in a calculation to get the result 28. You can use operations involving +, -, x, Γ·, ( ) as you wish.
Benjamin is about to turn 17. Let’s note that 17 = 8 + 9, and 172 = 289.
A Warming-Up Puzzle in Honour of Benjamin
In how many years from now will be the next (future) time that the square of Benjamin’s age then will end with the digits 89 on the right? π
As Brilliant Benjamin always gave 100% top efforts in my Maths class at the school, here comes…
A Modest Brainteaser in Honour of Benjamin here in Blog Post # 24+24+24+24+24+24+24 π
Part 1: I’m thinking of a particular number. If I add 2400 to the number, then its square root increases by exactly 16 (compared to the square root of the original starting number).
What number was I thinking of at the start?
Part 2: I am currently 61 years old. When can be the soonest (future) time that the square of my age then would end with the digits 89 on the right? Could there be yet another such time later on? π
Part 3: In Heaven, the good and joyful events will truly be infinite. As a sample taster, imagine a special feast of 289 celebrations there. Several celebrations before celebration #289, an angel announces that the square of that particular celebration number gives a number ending with the digits 89 on the right.
Given that information, and without even needing to use a calculator, deduce the exact celebration number when the angel’s announcement is made. β€οΈ

A Puzzle in Honour of Super Seinel π
Seinel’s birthday is not tomorrow! However, tomorrow it will be 41 days since her birthday, and we can still have some good Maths fun with that…!!
Think of any friend who’s less than 40 years old! Multiply their current age by the age they’ll be on their next birthday. Now add on the magic number 41.
What do you notice that’s special about all the results that can be obtained like that!?
A Nice Word Puzzle involving Seinel’s Prize Pen ππ
Rearrange the letters of SUPER SEINEL to make the word PENS + a proper seven-letter English word.
I wish you oodles of enjoyment with all the puzzles π, and please do feel free to send me your solutions by email, if you like. π
With kindest wishes as always,

I’ll conclude this Blog Post #168 with the beautiful Bible Psalm 16:8
“I have set the LORD always before me; because He is at my right hand, I shall not be shaken.”
