Q. Which number has same property as of the following numbers ? (957, 777, 876)

Explanation:

Observe the common property: the sum of digits of each given number is 21.
– 957: 9 + 5 + 7 = 21
– 777: 7 + 7 + 7 = 21
– 876: 8 + 7 + 6 = 21
Among the options:
– 999: 9 + 9 + 9 = 27 (not 21)
– 894: 8 + 9 + 4 = 21 (matches)
– 697: 6 + 9 + 7 = 22 (not 21)
– 979: 9 + 7 + 9 = 25 (not 21)
Hence, 894 (Option 2) shares the same property. (Equivalently, these numbers are divisible by 3 but not by 9, since digit sum 21 ≡ 3 mod 9.)
