A invested 125% as much money as B, C invested 80% as much money as B. The total of all the three is 61,000. How much did C invest?
Let x be the investment of B
From the given information, we have
Investment of A =125%ofx=1.25x
Investment of C =80%ofx=0.85x
Total of all the three =61,000
1.25x+x+0.8x=61,000
3.05x=61,000
x=610003.05
x=20000
Investment of C=80%of20000=0.8X20000=16000
Hence, C invested 16000
