Question

C. Find the simple interest by using the formula.
1. P=6400 R = 8% T = 2 years
2. P = 9200 R = 6% T = 3 years
3. P = 850 R = 12% T = 4 years
4. P= 10,000 R=4 1/2% T=2 years​

Answer 1

Answer:

1 SI=PTR/100

$= 6400 \times 8 \times 2 \div 100 \\ = 64 \times 8 \times 2 \\ = 512 \times 2 \\ = 1024$

SI=PTR/100

$= 9200 \times 6 \times 3 \div 100 \\ = 92 \times 6 \times 3 \\ = 9656$

SI=PTR/100

=850×12×4/100

=8.5×12×4

=408

SI=PTR/100

$10000 \times 4.5 \times 2 \div 100$

$= 100 \times 4.5 \times 2 \\ 10 \times 45 \times 2 \\ = 10 \times 90 \\ = 900$
