Answer 1

The savings of the sixth man is 1900

Step-by-step explanation:

The mean monthly savings of 6 Men are 2400

$Mean = \frac{\text{Sum of all observations}}{\text{No. of observations}}\\2400 = \frac{\text{Sum of savings of 6 men}}{6}\\2400 \times 6 = \text{Sum of savings of 6 men}\\14400= \text{Sum of savings of 6 men}$

the mean monthly savings those of five of them are 2500

$2500=\frac{\text{Sum of savings of 5 men}}{5}\\2500 \times 5 =\text{Sum of savings of 5 men}\\12500 =\text{Sum of savings of 5 men}$

Sixth man savings = 14400-12500

Sixth man savings =1900
