Question

find difference between ci and si on ₹8000 in 2 years at 5% per annum​

Answer 1

Step-by-step explanation:

$8000 \times 2 \times 5 \div 100 \\ 80 \times 2 \times 5 \\ 800 \\ 8000 + 800 = 8800 \\ ci = 8000 \times 1 \times 5 \div 10 \\ 400 \\ 8000 + 400 \\ 8400 \\ 8400 \times 1 \times 5 \div 100 \\ 84 \times 5 \\ 420 \\ 400 + 420 = 820 \\ difference = 820 - 800 = 20$
