ashish agarwal  (13 years ago)

I don't think the previous solution is acceptable since the the digits should be used only one. It is like this: If we have
A+B+C = =A*(A + 100*B + 10000*C + 10101)+100*(101*B + 100*C)
If {A,B,C} = {5,7,4}, then 5+7+4 = 364730
If {A,B,C} = {9,6,3}, then 9+6+3 = 456990
If {A,B,C} = {8,2,9}, then 8+2+9 = 912672
If {A,B,C} = {7,3,5}, then 7+3+5 = 503156
This is just a bad problem. BTW I did not know IAS has such kind of puzzles. Are you sure it was asked in IAS?

lakhinder mandi  (13 years ago)

for 5+7+4=36 47 30

first two digits of first answer comes by {(5+1)*4}+(5+7)=36

for 2nd two digits of first answer by {5*(7+1)}+7=47

for last two digits by 5*(5+1)=30 similarly 7+3+5=503156
ans is 503156

e.g
574 364730
L.H.S take the first integer and add 1 which is now 6
R.H.S
6*(first digit) 30
6*(second digit) + first digit 47
6*third digit + first and second digit 36

same case applies for second, third and fourth, so answer is 503156.

According to question,

30 = 5 * ( 5 + 1)
47 = ( 7 * 6 ) + 5
36 = ( 4 * 6 ) + ( 5 + 7)

90 = 9 * ( 9 + 1)
69 = ( 6 * 10 ) + 9
45 = ( 3 * 10 ) + 9 + 6

72 = 8 * ( 8 + 1 )
26 = ( 2 * 9 ) + 8
91 = ( 9 * 9 ) + 8 + 2
On calculation,

7 + 3 + 5
=> 7 * ( 7 + 1 ) = 56
=> ( 3 * 8) + 7 = 31
=> ( 5 * 8 ) + 7 + 3 = 50

therefore, the answer is 503156.

bala  (8 years ago)

Answer is 503156.
50 = 7*5+(7+3+5)
31 = 7*3+(7+3)
56 = 7*7 + 7

Dineshkumar.M  (8 years ago)

Example: 5+7+4=364730
consider A+B+C=??????
So, A=5,B=7,C=4
1st two digit 36= (A+B+C)+(A*C)
2nd two digit 47=(A+B)+(A*C)
3rd two digit 30=(A)*(A+1)
like wise
7+3+5=503156

Mahesh Muttigi  (7 years ago)

(5*4)+(5+7+4)=36,(5*7)+(5+7)=47,(5*5+5)=30...we will get 364730
Like wise for 7+3+5 we will get as (7*5+(7+3+5))=50,(7*3)+(7+3)=31,(7*7+7)=56....so the answer is 503156

sneha patil  (7 years ago)

5*(5+1)=30
9*(9+1)=90
8*(8+1)=72

like
7*(5+1)+5=47
6*(9+1)+9=69
2*(8+1)+8=26

4*(5+1)+5+7=36
3*(9+1)+9+6=45
9*(8+1)+8+2=91



therefore 7+3+5=503156
