- Ok Vlad
- I will teach you to solve problems in each concept and I will tell what is compound interest
- For finding percentage we have a formulaP=PARTS/WHOLE*100%
- what is compound interest?
- For finding discount we have a formuladiscount=C.P-S.P
- .
- Eg :C.P=840 S.P=714 = 840-714 =126
- .
- Eg;P=17W=40
- 17/40=.425*100%=42.5%
- Vlad: I hope you understand the concept well
- Compound interest is the interest calculated on the principal and the interest accumulated over the previous period. It is different from simple interest, where interest is not added to the principal while calculating the interest during the next period. In Mathematics, compound interest is usually denoted by C.I.
