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 🙂
