    D) Rs 32000

    Correct Answer: B

    Solution :

    Ans.     Total salary of three person A, B, and C = Rs 144000 Let the ratio of their salaries = a: b: c Then, \[\frac{a\times (100-80)}{100}:\frac{b\times (100-85)}{100}:\frac{c\times (100-75)}{100}\] \[:\,\,:\,\,\,8\,\,:\,\,9:20\] \[\frac{a\times 20}{100}:\,\frac{b\times 15}{100}:\frac{c\times 25}{100}::\,\,8:\,9\,:\,20\] \[\frac{a}{5}:\frac{b\times 3}{20}:\frac{c}{4}::\,\,8\,:\,9:\,20\] \[a & \,:\,b:\,c::40:60:80\] So C? salary \[=\frac{80}{180}\times 144000\,\,\,\Rightarrow \,\,\,=\,\,64000\]
