A 809Each word in the statements refer to a number. We have 5 statements
1) SKY WAS BLUE = 123
2) SEA IS BLUE = 245
3) PEOPLE SWIMMING IN SEA = 4678
4) PEOPLE LIKE SKY = 801
5) BIRDS IN SKY = 169
In statements 3 and 4, only common word is PEOPLE and only common number is 8. Hence PEOPLE is represented by 8
In statements 1, 4 and 5, the common word is SKY and the only common number is 1. Hence SKY is represented by 1
In statements 3 and 5, the common word is IN and the only common number is 6. Hence IN is represented by 1
In statement 5, IN is represented by 1, SKY is represented by 6. Hence, BIRDS is represented by 9
In statement 4, PEOPLE is represented by 8, SKY is represented by 1. Hence, LIKE is represented by 0
Therefore PEOPLE LIKE BIRDS will be represented by the combination of numbers 8,0 and 9
