Interesting Maths Problems

4 + 7 + 2 = 2814357 + 3 + 9 = 2127816 + 2 + 7 = 1214562 + 8 + 5 = 1640368 + 4 + 6 = ??????

This question is quite tricky, everyone has to look at very carefully for answers:

First four digits are easy to find by looking at digit patterns:

Multiplication of First and Second digits of question will find out the first and second digits of the answer.

Multiplication of Second and Third digits of question will find out the third and fourth digits of the answer.

i.e. 4 + 7 + 2 = (4×7) (7×2) = 2814 or 7 + 3 + 9 = (7 x 3)(3×9) = 2127 ….

so 8 + 4 + 6 = (8×4) (4×6) = 3224??

Now the real question how to find out the 5th and 6th digits:

If we observe each fifth digit of answer with the first digit of question we can relate that it follows -1/+1 form

means Fifth digit is coming from the first digit of a question but once -1 and for next number +1 like that.

Look at this pattern:

4+7+2=281435 (4–1=3=fifth digit)

7+3+9=212781 (7+1=8=fifth digit)

6+2+7=121456 (6–1=5=fifth digit)

2+8+5=164036 (2+1=3=fifth digit)

Now coming to the fifth digit of answer we have

8+4+6= 32427_ (8–1=7=fifth digit)

We did -1 from first digit of question because in previous number we did +1.

Now we got the fifth digit.

How to find the 6th digit?

It’s a tricky one:

To find 6th digit of answer we have to use this formula

(first digit x second digit) + (second digit x third digit) + (third digit+first digit)

Whatever will be the answer we will take the first digit of the above formula as an answer(for 6th digit)

4 + 7 + 2 = (4×7) + (7×2) + (2×4) = 28+14+8 = 50,

So we will take 5(first digit) and igonre the other digit so our 6th digit is 5.

4 + 7 + 2 = 281435

simillarly:

7 + 3 + 9 = (7×3) + (9×3) + (9×7) = 111,

So we will take 1(first digit) and igonre the other digits so our 6th digit is 1.

7 + 3 + 9 = 212781,

next,

6 + 2 + 7= (6×2) + (2×7) + ( 7×6) = 68

So we will take 6(first digit) and igonre the other digit so our 6th digit is 6.

6 + 2 + 7 = 121456

Now go to the solution of our question simillarly:

8 + 4 + 6 = ??????

32247?

We have found out to 5th digit

8 + 4 + 6 = (8×4) + (4×6) + (6×8) = 104

So we will take 1(first digit) and igonre the other digits so our 6th digit is 1.

7 + 3 + 9 = 212781.
