A. 10% B. 20% C. 33 1/2 D. None Of These ?

Q.Find the compound interest of principal amount Rs 50000 at the rate 5% for 3 3/4 years?

Q. ax+by+c = 0 is the linear equation in variable -------------------

Q. Solve
(a) x-2[3x -2(x+1)+5]=16
(b) 4(3x -2)= 7 (2-5x)-5

Q. What is the interest on Rs 1880.90 for one year @ 5 1/2 % ?

Plz Answer Someone ???

ans 2
(5000*5*1)/100 = 250 now add 250 to 5000 = 5250
(5250*5*1)/100 = 262.5 = 5250+262.5= 5512.5
(5512.5*5*1)/100=275..625 = 5512.5+275.625= 5788.12
(5788.12*5*0.75)/100 = 289.41
5788.12+289.41=6077.53<-----ur compound interest

last ques ans
(1880.90*1*5.5)/100=103.45
