Ok Thank you Riya I will cometo park
See Rohan we have 3 main concepts in comparing quantities1.Discount2.Percentage3.Compound interest
They both came to parkRiya started to teach Rohan
.
Ok Riya
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%
Riya: 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.

Rohan :Ya, Thanks Riya for teaching me
