Problem Statement: Five three digit numbers including N, were to be added. While adding, the reverse of N was added by mistake instead of N. Hence, the sum increased by 11 times the sum of the digits of N. Eight times the difference of N's units and hundreds digits is 6 more than twice its hundreds digit. Find its tens digit.
Solution:
Let the three-digit number N be represented as ABC, where A, B, C are the hundreds, tens, and units digits, respectively.
Step 1: Express the given conditions mathematically.
The sum of the five three-digit numbers, including N, is:
ABC + DEF + GHI + JKL + LKJ = 1000A + 100B + 10C + 100D + 10E + F + 100G + 10H + I + 100J + 10K + L + 100L + 10K + J = 1111(A + D + G + J + L) + 101(B + E + H + K) + 11(C + F + I)
When the reverse of N, which is CBA, is added instead of N, the sum becomes:
CBA + DEF + GHI + JKL + LKJ = 1000C + 100B + 10A + 100D + 10E + F + 100G + 10H + I + 100J + 10K + L + 100L + 10K + J = 1111(C + D + G + J + L) + 101(B + E + H + K) + 11(A + F + I)
According to the problem, the sum increased by 11 times the sum of the digits of N. Therefore, we have:
11(A + B + C) = 1111(C + D + G + J + L) + 101(B + E + H + K) + 11(A + F + I) - 1111(A + D + G + J + L) - 101(B + E + H + K) - 11(C + F + I)
Simplifying the above equation, we get:
10A - 100C = 1100L - 1100D + 100J - 100G + 10I - 10F + 11C - 11A
Also, it is given that:
8(C - A) = 2A + 6
Step 2: Solve the equations to find the value of B.
Using the second equation, we can express A in terms of C as:
A = (4C - 3)/5
Substituting this value of A in the first equation, we get:
8C - 10B - 108 = -100D + 100G - 10I + 10F + 112L
Simplifying the above equation, we get:
4C - 5B - 54 = -50D + 50G - 5I + 5F + 56L
Using the fact that A, B, C are digits, we know that 0 ≤ A ≤ 9, 0 ≤ B ≤ 9, and 1 ≤ C
Solution:
Let the three-digit number N be represented as ABC, where A, B, C are the hundreds, tens, and units digits, respectively.
Step 1: Express the given conditions mathematically.
The sum of the five three-digit numbers, including N, is:
ABC + DEF + GHI + JKL + LKJ = 1000A + 100B + 10C + 100D + 10E + F + 100G + 10H + I + 100J + 10K + L + 100L + 10K + J = 1111(A + D + G + J + L) + 101(B + E + H + K) + 11(C + F + I)
When the reverse of N, which is CBA, is added instead of N, the sum becomes:
CBA + DEF + GHI + JKL + LKJ = 1000C + 100B + 10A + 100D + 10E + F + 100G + 10H + I + 100J + 10K + L + 100L + 10K + J = 1111(C + D + G + J + L) + 101(B + E + H + K) + 11(A + F + I)
According to the problem, the sum increased by 11 times the sum of the digits of N. Therefore, we have:
11(A + B + C) = 1111(C + D + G + J + L) + 101(B + E + H + K) + 11(A + F + I) - 1111(A + D + G + J + L) - 101(B + E + H + K) - 11(C + F + I)
Simplifying the above equation, we get:
10A - 100C = 1100L - 1100D + 100J - 100G + 10I - 10F + 11C - 11A
Also, it is given that:
8(C - A) = 2A + 6
Step 2: Solve the equations to find the value of B.
Using the second equation, we can express A in terms of C as:
A = (4C - 3)/5
Substituting this value of A in the first equation, we get:
8C - 10B - 108 = -100D + 100G - 10I + 10F + 112L
Simplifying the above equation, we get:
4C - 5B - 54 = -50D + 50G - 5I + 5F + 56L
Using the fact that A, B, C are digits, we know that 0 ≤ A ≤ 9, 0 ≤ B ≤ 9, and 1 ≤ C
