Question

Answer the 3 and 4th question

Answer 1

3rd answer:

P=1200
T=4 years
R=10%
I =PTR/100
=1200×4×10/100
=480Rs
interest to be paid =480Rs
amount=I+P
amount=480+1200
=1680Rs
amount to be paid after 4 years =1680Rs


4th answer:

cost borred by suresh=6000Rs
returned cost =7500Rs
interest =7500-6000
=1500Rs
interest=PTR/100
1500=6000×2×R/100
1500=120×R
1500÷120=R
12.5=R

rate of interest =12.5%

check:I=PTR/100
I=6000×2×12.5/100
I=1500Rs
amount to be paid=6000+1500=7500

hope both the answers helps u...
