The new mean is 140

Step-by-step explanation:

The mean of 75 numbers is 35

$Average = \frac{\text{Sum of all observations}}{\text{No. of observations}}$

$35 = \frac{\text{Sum of 75 numbers}}{75}$

$35 \times 75 =\text{Sum of 75 numbers}$

$2625 =\text{Sum of 75 numbers}$

Each number is multiplied by 4

So, New mean = \frac{4(2625)}{75}=140

Hence The new mean is 140
