Question 1.
Solution:
Principal (P) = Rs. 6250
Rate of (R) = 4% p.a.
Period (T) = 6 months = $$\frac { 1 }{ 2 }$$ year Question 2.
Solution:
Amount (A) = Rs. 3605
Rate (R) = 5% p.a.  Question 3.
Solution:
Let sum (P) = Rs. 100 Question 4.
Solution:
Principal (P) = Rs. 8000
Amount (A) – Rs. 8360
S.I. = A – P = Rs. 8360 – Rs. 8000 = Rs. 360
Rate (R) = 6% p.a. Question 5.
Solution:
Let sum (P) = Rs. 100
Then amount (A) = Rs. 100 x 2 = Rs. 200
S.I. = A – P = Rs. 200 – Rs. 100 = Rs. 100
Period (T) = 10 years Question 6.
Solution:
S.I. = Rs. x
Rate (R) = x% p.a.
Time (T) = x year Rs. $$\frac { 100 }{ x }$$ (c)

Question 7.
Solution:
Let sum (P) = Rs. 100 Question 8.
Solution:
A’s principal (P) = Rs. 8000
Rate (R) = 12% p.a.
B’s principal = Rs. 9100
Rate = 10%
Let after x years, then amount will be equal  Question 9.
Solution:
Amount (A) = Rs. 720
Principal (P) = Rs. 600
S.I. = A – P = Rs. 720 – 600 = Rs. 120
Period (T) = 4 years Question 10.
Solution: Question 11.
Solution:
Let sum (P) = Rs. 100
Their S.I. = 0.125 of Rs. 100 Question 12.
Solution:
S.I. = Rs. 210 Hope given RS Aggarwal Solutions Class 7 Chapter 12 Simple Interest Ex 12B are helpful to complete your math homework.
