Answer:
100,000
Step-by-step explanation:
Investment ratio = 3 : 2
Rate = 5% and 4% simple interest
Total interest after 2 years = 9200
Let total investment = t
(3/5t * 0.05 * 2) + (2/5t * 0.04 * 2) = 9200
3/5t * 0.1 + 2/5t * 0.08 = 9200
0.06t + 0.032t = 9200
0.092t = 9200
t = 9200 / 0.092
t = 100,000
