They spend 80%, 85% and 75% respectively. If their savings are in the ratio 8: 9: 20, find C's salary, A) Rs 48000                     B) Rs 64000 C) Rs 40000                     D) Rs 32000

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 $=\frac{80}{180}\times 144000\,\,\,\Rightarrow \,\,\,=\,\,64000$
