Question

se depune suma de 285 000 u.m cu rata dobanzii simple de 1,5. Ce suma se va obtine dupa : a) 4 luni...b) 9 luni

Answer 1

4luni=1/3 ani
dauas=285000*1.5%:3=285 000*0,5%=285*5=1425
suma totala 285000+1425=296 425


9 luni =4*9/4=2,25*4luni deci adausul =1425*4=3206,25
suma total dupa 9 luni=285000+3206,25=288 206,25

Answer 2

dobanda simpla este de 1,5%/an, vom avea
a) D=(285000x1.5)/100=4275/an  la 4 luni D4=(4275/12)x4=1425, deci dupa 4 luni suma totala va fi de 285000+1425=286425 u.m.
b) la 9 luni D9=(4275/12)x9=3206,25, suma totala=285000+3206,25=288206,25 u.m.
