Question

Write all important formulae of simple and compound interest .

Answer 1

compound interest = A - P

Answer 2

Hey !!!

☢If p stand for principle , R the rate percent per annum , T the time number of years , A the amount and SI the simple interest , then

SI = P × R × T /100

☢ let principle = ₹P , Rate = R%per annum

Time = n years

( ! ) When interest is rockoned annually
Amount = P ( 1 + R/100)ñ

( !! ) When interest is annually and rate of interest be R¹% during 1st year R² % during 2nd year , R³ % during 3rd year

Amount = P × ( 1 + R1/100) (1 + R² /100) ( 1 + R³ /100]

(!!!) When interest is half - yearly

Amount = P ×[1+R/2×100]²ñ

4 ] When intrest is quarterly

Amount = P × (1 + R/4×100)4ñ
