Answer:
PLZ MARK AS BRAINLIST IF HELPED
Step-by-step explanation:
Here,
P = Rs 40000
A = Rs 4576.50
T = 2 years
Interest = Amount – Principal
= Rs 4576.50 – Rs 4050
= Rs 526.50
Let the rate of simple interest = R% per annum
Then,
R = (I × 100) / (P × T)
= (526.50 × 100) / (4050 × 2) % p.a.
On further calculation, we get,
= (526.50 × 10) / (405 × 2) % p.a.
= 5265 / 810 % p.a.
We get,
= 6.5% p.a.
Now,
P = Rs 1 lakh
= Rs 100000
R = 6.5% p.a.
T = 3 years
I = (P × R × T) / 100
= Rs (100000 × 6.5 × 3) / 100
We get,
= RS 1000 × 6.5 × 3
= Rs 19500
Amount = Principal + Interest
= Rs 100000 + Rs 19500
= Rs 119500
