Answers
Answer:
3600×4×6÷100= 864
A=3600+864=4464
Step-by-step explanation:
SI=P×T×R% (P=3600,T=4
YEAR, RATE= 6%)
SI=3600×4×6÷100=864
AMOUNT = P+SI
AMOUNT =3600+864=4464
Answer:
Rs 15000
Step-by-step explanation:
A sum of money was invested at Simple interest at certain rate for 4 years.
If the rate was 6% higher than the initial , it could have fetched Rs 3600 more.
So, according to the problem,we know that
S.I= (p * r * t)/100
p=principal money, r= rate of interest, t= time
So now considering 6% higher rate would have fetched rs 3600 more, now the rate becomes 6+r.
Hence according to the given problem , we can deduce:
p*(r+6)*4 p*r*4
_________ - _______ = 3600
100 100
4pr+24p 4pr
_______ - _____ =3600
100 100
24p/100 =3600
24p= 3600 * 100
p= (3600 *100)/24
p= 15000
Therefore the sum of money invested was Rs 15000.
