Hello Friend ,

us assume that their savings are 8k, 9k and 20k respectively.
A spends 80% of his salary. Thus he saves (100 – 80 = 20%) of his salary. So, 20% = 8k. Therefore, A’s total salary i.e. 100% = 40k.
B spends 85% of his salary. Thus he saves (100 – 85 = 15%) of his salary. So, 15% = 9k. Therefore, B’s total salary i.e. 100% = 60k.
C spends 75% of his salary. Thus he saves (100 – 75 = 25%) of his salary. So, 25% = 20k. Therefore, C’s total salary i.e. 100% = 80k.
According to the question, 40k + 60k + 80k = 1,44,000
180k = 144000
k = 800
Thus, C’s salary = 80k = 80 x 800 = 64,000 (Answer)
