Answer to the Maths Puzzle:
The solution to the first 4 digits is pretty straight forward, and I am sure most of you must have easily got it.
It works out to be a+b+c = (a*b)(a*c)??
The last 2 digits are really tough to crack…
Here’s how you do it.
The last 2 digit is equal to (a*b)+(a*c)-b
If we test this formula for the first equation i.e. 5 + 3 + 2 = 151022
(axb) = (5×3) = 15;
(axc) = (5*2) = 10;
(a*b)+(a*c)-b = (5×3)+(5×2)-3 = 15 + 10 -3 = 22
Similarly this equation will fit all other equations in the sequence.
To find 7 + 2 + 5 = ??????
We use the same formula;
(axb) = (7×2) = 14;
(axc) = (7*5) = 35;
(a*b)+(a*c)-b = (7×2)+(7×5)-2 = 14 + 35 – 2 = 47
Hence 7 + 2 + 5 = 143547
143547
14+35
49
49-2
47
thankyou
Very funny but your answer is wrong for maths puzzle….
To find 7 + 2 + 5 = ??????
We use the same formula;
(axb) = (7×2) = 14;
(axc) = (7*5) = 35;
(a*b)+(a*c)-b = (7×2)+(7×5)-2 = 14 + 35 – 2 = 46
Hence 7 + 2 + 5 = 143546
The answer is not 143546
But 143547
Thanks for pointing out the error 🙂
