    BRAINLIEST ANSWER

    Step-by-step explanation:

    Friends…!

    First we have to find out the sum of all 75 numbers

    Mean = Sum / number of numbers

    Sum = mean × no. of numbers

    Sum = 35 × 75 = 2625

    Each number is multiplied by 4

    After multiplication of 4 in each number, their sum will be

    2625 × 4 = 10500

    Mean = sum/no of numbers

    Now their new mean = 10500/75

    Mean = 140
