Step-by-step explanation:
first we will form the investments with time period in ratio . i.e.
50000×6 : 60000×4 : 80000×5
5×6 : 6×4 : 8×5
5×3: 3×4: 4×5
15 : 12 : 20
now
share of A =[ 15/(15+12+20)]×18800
=(15/47)×18800
=15×400
=6000
share of B =[ 12/(15+12+20)]×18800
=(12/47)×18800
= 12×400
=4800
share of C =[ 20/(15+12+20)]×18800
=(20/47)×18800
= 20×400
=8000
