The present worth of Rs. 1404 due in two equal half-yearly installments at 8% per annum simple interest is:
A. Rs. 1325 B. Rs. 1300
C. Rs. 1350 D. Rs. 1500
Read Solution (Total 5)
-
- time=1/2yr
r=8%
let pw=x
si=1404-x
x*1/2*8/100=1404-x.(ref problm 10 of SI ,rs aggarwal)
x=1404*25/26
hence x=1350 - 11 years agoHelpfull: Yes(7) No(6)
- can any one give explnation for this?
- 11 years agoHelpfull: Yes(6) No(5)
- Required sum = P.W. of Rs. 702 due 6 months + P.W. of Rs. 702 due 1 year hence
= Rs. 100 x 702 +
100 x 702
100 + (8 x 1)
100 + 8 x
= Rs. (675 + 650)
= Rs. 1325. - 10 years agoHelpfull: Yes(3) No(0)
- present worth=x/(1+r/100)^n
given,x=1404,r=8%,n(time in year)=1
p.w=1404/(1+8/100)^1
p.w=1404/(27/25)
p.w=1404*25/27
p.w=1300 - 11 years agoHelpfull: Yes(2) No(11)
- PW=(100*Amnt)/100+(R*T)
Amnt=1404,R=8,T=1/2
sub the value to get PW=1350 - 10 years agoHelpfull: Yes(1) No(1)
