Answer 143547 2) Find three positive whole numbers that have the same answer added 6) Replace the ‘?’ by any mathematical together or when multiplied symbol to make the expression together? equal to 111. 18?12?2?3=111. Answer Answer 1,2&3. 18×12÷2+3=111. 1×2×3=6 and 1+2+3=6. 7) Today my car meter reads as 72927 3) When Deepak was six years old he kms. I notes that this is a hammered a nail into his favourite palindrome. How many minimum tree to mark his height. Five years kms I need to travel so my car meter later at age eleven, Deepak returned find another palindrome. to see how much higher the nail was. If the tree grew by ten inches each Answer year, how much higher would the 110 kms. nail be? 72927+110=73037, a palindrome. Answer The nail would be at the same height 8) Can you arrange for nines to make it since trees grow at their tops. equal to 100.

How many times will 9) What is the value of 1/2 of 2/3 of Ramesh have to paint the number 3/4 of 4/5 of 5/6 of 6/7 of 7/8 of eight? 8/9 of 9/10 of 1000? Answer Answer 20 times. 100. Look hard? Just work it 8,18,28,38,48,58,68,78,80,81,82,83,8 backwards. You found it easy. 4,85,86,87,88,89,98.

5) 5+3+2=151022


NUMBER PUZZLES we’ve used that already. So B=1 21CD8*4 = 8DC12  To get the 1 that’s on the right-hand side, D*4+3 when divided by 10 must leave a remainder of 1. D can’t be 2 (2 has been used already) so D=7 21C78*4 = 87C12  4*C+3 when divided by 10 must give the answer 3 and a What 5 digit number(where the remainder C, so C=9 digits are all different and none of 21978*4 = 87912 . them is zero) multiplied by 4 gives an answer where the digits are those This sum uses all the digits from 0 of the original number but in reverse to 9 order? 28* Answer + **4 21978. ABCDE*4 = EDCBA **** Let’s start at the ends.  A can only be 1 or 2, because Answer A*4<10. E*4 divided by 10 289+764 = 1053. must leave a remainder of A. It can’t leave a remainder of 1, so A=2 2BCDE*4 = EDCB2  If E*4 divided by 10 leaves a remainder of 2, then E has to be 3 or 8. The E on the right- hand side must be 8 or 9. Putting those 2 constraints together, E=8 2BCD8*4 = 8DCB2  B*4 must be < 10. If it was more, then the first digit of ♠♠♠♠♠♠ the right-hand side wouldn’t be 8. B can’t be 2 because
