a) Total Sales of salesman A = Rs. 18000

`"Sales of salesman A"=" Central angle"/(360°) xx "total sale"`

⇒ `18000=(90°)/(360°)xx "Total sales"`

⇒ `"Total sale" = (18000 xx 360)/90`

⇒ Total sale = Rs. 72,000

b) `"Sales of salesman B"=" Central angle"/(360°) xx"total sale"`

`"Sales of salesman B"=(120°)/(360°)xx72000`

`"Sales of salesman B"="Rs".24000`


`"Sales of salesman c"="Central angle"/(360°)xx"Total sales "`

`"Sales of salesman C"=(80°)/(360°)xx72000`

`"Sales of salesman C"= "Rs."16000`


`"Sales of salesman D"="Central angle"/(360°)xx"Total sales "`

`"Sales of salesman D"=(70°)/(360°)xx72000`

`"Sales of salesman C"= "Rs."14000`

c) Salesman B has the highest sale of Rs 24,000.

d) Highest sale = Rs. 24,000
Lowest sale = Rs. 14,000
∴ Difference between the highest sale and the lowest sale = 24000 − 14000 = Rs. 10,000.
