Answer:
R = (3. 1/3) % P = Rs. 3375
Step-by-step explanation:
In 6 years sum amounts to = Rs. 4050
In 4 Years sum amounts to = Rs. 3825
∴ Interest of 2 years = Rs. 4050 – Rs. 3825
= Rs. 225
Interest of 4 years = Rs. (225/2) × 4
= Rs. 450
(∵ Rs. 225 is interest for 2 years)
Now P = A – I
= Rs. 3825 – Rs. 450
= Rs. 3375
I = Rs. 450
T = 4 years
R = (100 × I)/(P × T)
= (100 × 450)/(3375 × 4)
= (45000/13500) % = (450/135) %
= (10/3) % = (3. 1/3)%
R = (3. 1/3) %
P = Rs. 3375
