Answer:

Total salaries of A, B and C = Rs. 14400

Let the salaries of A, B and C be Rs. x, Rs. y and Rs. z respectively.

∴x+y+z=14400 ......... (1)

Their spendings are 80%, 85% and 75% respectively,

∴ Their savings are 20%, 15% and 25% respectively and also their savings are given in the ratio 8 : 9 : 20
