The image contains three math-related problems in Indonesian. Here’s a translation and breakdown of each question:

1. Virus Growth

A laboratory test shows that 1 virus can divide into 2 viruses in 4 hours. In the test, there were initially 200 viruses. Determine the number of viruses after 12 hours!

2. Farmer’s Crop Yield

A farmer records the yield of his crops for the last 10 years. It turns out that the yield increases by 10% each year. If in the first year the crop yield was 10 tons, determine the crop yield in the fourth year!

3. Bank Savings

Mrs. Dewi deposits Rp5,000,000 in a bank and earns 10% interest per year. If the interest remains fixed and she never withdraws money, how much will Mrs. Dewi's savings be after 6 years?

Would you like me to provide detailed solutions to these questions?
