A) 2
B) 3
C) 3.5
D) 4
Correct Answer: D
Solution :
[d] Here, P=400 A=448 T=2years R=? \[\therefore \]A=P+S.I \[\therefore \]S.I=\[A-\,P\] \[=448-\,400=48\] \[48=\frac{400\times R\times 2}{100}\] \[\therefore \,\,\,R=\frac{48\times 100}{400\times 2}=6%\] Now P=550 A=682 R=6% T=? \[\therefore \,\,\,S-\,I=682-\,550=132\] \[\therefore \,\,\,132=\frac{550\times 6\times T}{100}\] .\[\therefore \,\,\,T=\frac{132\times 100}{550\times 6}=4\,\,Year\]You need to login to perform this action.
