A sum of Rs. 2900 amounts to Rs. 3422 in 3 years. Had the rate of interest be 3% higher then what would the sum amount in the same time period?
(a) Rs. 4465
(b) Rs. 3683
(c) Rs. 3596
(d) Data inadequate
(e) None of these
Read Solution (Total 5)
-
- B) 3683
3422=2900+(2900*R*3/100)
R=6
If R is 3 more.
Then R=9
Sum=2900+(2900*9*3/100)
Sum=3683 - 8 years agoHelpfull: Yes(21) No(2)

- Answer (b) Rs. 3683
- 7 years agoHelpfull: Yes(0) No(2)
- Rent per square foot per year=2244/(18×22)×12=(102×12)/18=(102×2)/3=Rs.68

- let rate of interest =r
interest =i=3422-2900=522
r=(i*100)/(sum*t)
r=6%
updated value of r=6+3=9%
total ammount will be 2900 + interest on 9% for 3 years
i.e. 3683 - 7 years agoHelpfull: Yes(0) No(0)
