Ram is going
= (18+1+13), (9+19), (7+15+9+14+7) (According to positions of alphabets)
= 32, 28, 52
= 5, 10, 7 (Sum of the digits of the number)
= 5, 1, 7 (Sum of the digits of the number)
= 5-1+7
= 11
= 2 (Sum of the digits of the number)
Similarly Mohan was singing
= (13+15+8+1+14), (23+1+19), (19+9+14+7+9+14+7)
= 51, 43, 79
= 6, 7, 16
= 6, 7, 7
= 6-7+7
= 6
Take similar steps for �Birds are flying� we get
(2+9+18+4+19), (1+18+5), (6+12+25+9+14+7)
= 52, 24, 73
= 7, 6, 10
= 7, 6, 1
= 7-6+1
= 2
