    Solution

    Remainder obtained when 34 × 46 × 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 ÷ 25 → remainder = 9
    46 ÷ 25 → remainder = 21
    52 ÷ 25 → remainder = 2

    So, required remainder = 9 × 21 × 2 = 378

    Now, 378 ÷ 25 leaves remainder = 3 .

    So, required remainder is 3 .
