jomon v j  (11 years ago)

let x be the principal and y be the interest rate. given two years S I is 800

ie 2xy/100 = 800

xy = 40000

also given C I is 832

ie x + xy/100 +( x+xy/100)y/100 - x =832

substuting xy =40000 and simplifying

400 + 400 +4y =832

y= 8 and x=5000

so calculating C I for 3 years is 1298.56 and obviusly S I is 400*3 =1200

so difference is 98.56
