check the cyclicity.
Alternate method:
We have to find out (1273)^122! mod 10
=(3)^122! mod 10
=(3)^0 mod 10 {E(10)=4, 122! mod 4=0}
=1 mod 10

122! mod 4 =0
so 3^4=81 so ans =1

122! will be always divide by 4..
so 122! mod 4 = 0
3^0=1

1000x + 100y + 10z + w = 2010
x = 2,
10z + w = 1, so 2 ways
x = 1,
100y + 10z + w = 1010
y = 0, 10z + w = 1010, 8 ways
y = 1, 10z + w = 910, 10 ways
.
y = 9, 10z + w = 110, 10 ways
y = 10, 10z + w = 10, 2 ways
total = 100 ways
x = 0
100y + 10z + w = 2010
y = 10, 11, 12, ..., 20
case will be same as x = 1
So, total 2 + 100 + 100 = 202 ways

Clearly (a3)
1) a3 = 2
10 = 100a2 + 10a1 + a0
=> a2 has to be zero => 10a1 + a0 = 10 => 2 cases
2) a3 = 1
1010 = 100a2 + 10a1 + a0
a2 = 0 => 10a1 + a0 = 1010 => a1 = 92 to 99 (8 cases)
a2 = 1 => 10a1 + a0 = 910 => a1 = 82 to 91 (10 cases)
a2 = 2 => 10a1 + a0 = 810 => a1 = 72 to 81 (10 cases)
and so on..
a2 = 9 => 10a1 + a0 = 110 => a1 = 2 to 11 (10 cases)
a2 = 10 => 10a1 + a0 = 10 => 2 cases
3) a3 = 0
2010 = 100a2 +10a1 + a0
Max value of 10a1 + a0 can be 1089, so min value for a2 = 10
a2 = 10 => 10a1 + a0 = 1010 => 8 cases (same as case when a3 = 1)
...similar cases will come up here too (as in case of a3 = 1)
So, total cases = 2 + (8 +2 + 10*9)*2 = 202 ?

Once you know the approach, it won't take much time :). All these type of questions have the same method of rotating the integers in a range. The number of cases always tend to follow a pattern, if they don't, then leave it 😛

5a + 4m = 36*9
7a + 8m = 48*15
Adding,we get 12*(a + m) = 36*9 + 48*15
Now, 24*(a + m) = 2*36*(9 + 20) = 72*29 = 2088 ?

Avg cost of 5 apples and 4 mangoes = Rs. 36
Total cost = 36 * 9 = 324
Avg cost of 7 apples and 8 mangoes = 48
Total cost = 48 * 15 = 720
Total cost of 12 apples and 12 mangoes = 324 + 720 = 1044
Therefore, cost of 24 apples and 24 mangoes = 1044 * 2 = 2088
Total cost = 36 * 9 = 324
Avg cost of 7 apples and 8 mangoes = 48
Total cost = 48 * 15 = 720
Total cost of 12 apples and 12 mangoes = 324 + 720 = 1044
Therefore, cost of 24 apples and 24 mangoes = 1044 * 2 = 2088

5A+4M=36*9

adding these two
12A+12M=1044
24A+24M=2088?
