Solution

The correct option is A 48000
Let us assume that their savings are 8k,9k and 20k respectively.
A spends 80% of his salary. Thus he saves (10080=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 (10085=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 (10075=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
k=800
Thus, C's salary = 80k=80×800=64,000
