Question

4+7+2=281435, 7+3+9=212781, 6+2+7=121456, 2+8+5=164036, 8+4+6=?????? how possible

Answer 1

★ Here is Your answer ★

♦ 4+7+2=281435

Taking this,

First two digit(1 and 2) = multiplication of first two numbers.

i.e. 4 *7= 28

Next two digit(2 and 4) = multiplication of last two numbers

i.e. 7*2=14

this is same in every code

•so here we can get first four digit of our answer,

i.e. 8+4+6= 3242__

Now, for fifth digit,

•if we observe each fifth digit of answer with first number we can relate that it follows -1/+1 form

i.e. 1. 4+7+2=281435 (4–1=3=fifth digit)

2. 7+3+9=212781 (7+1=8=fifth digit)

3. 6+2+7=121456 (6–1=5=fifth digit)

4. 2+8+5=164036 (2+1=3=fifth digit)

•Now coming to fifth digit of answer we have

8+4+6= 32427_ (8–1=7=fifth digit)

Now for the last 6 digit we have take the product of all numbers and have to consider first digit of answer and if the digit is odd we have to take the same and if it is even we have to subtract 2, let take it practically,

4+7+2=281435=4*7*2=56 (first digit=5(odd number)=six digit of answer)

7+3+9=212781=7*3*9=189(first digit=1(odd)=six digit of answer)

6+2+7=121456=6*2*7=84 (first digit=8(even)=8–2=6=six digit)

Hence, six digit of answer to 8+4+6

8*4*6=192

First digit 1(odd)

Therefore,

8+4+6=324271 ....
