Question
Find the remainder obtained when 34 Γ 46 Γ 52 is
divided by 25.Solution
Remainder obtained when 34 Γ 46 Γ 52 is divided by 25 will be equal to the product of remainders obtained when 34, 46, and 52 are divided individually by 25.
Therefore,
34 Γ· 25 β remainder = 9
46 Γ· 25 β remainder = 21
52 Γ· 25 β remainder = 2
So, required remainder = 9 Γ 21 Γ 2 = 378
Now, 378 Γ· 25 leaves remainder = 3 . So, required remainder is 3 .
