Sara deposited Rs 1435 for 3 years and 9 months at tge rate of 5 % p. a. Find the amount at maturity
Answers
Solution :-
P = Rs. 1435
R = 5 %
T = 3 years and 9 months
First the compound interest for 3 years will be calculated and then the amount after 3 years will be considered as principal and on this principal the simple interest for 9 months will be calculated.
Compound interest for 3 years -
A = P (1 + R/100)ⁿ
⇒ 1435 (1 + 5/100)³
⇒ 1435*21/20*21/20*21/20
⇒ 13289535/8000
= Rs. 1661.19
Now for the next 9 months the principal will be Rs. 1661.19
Simple Interest = (P*R*T)/100
⇒ (1661.19*5*9)/(12*100)
⇒ 74753.55/1200
S.I. = Rs. 62.29
Amount = P + I
A = 1661.19 + 62.29
= Rs. 1723.48
So, amount at maturity will be Rs. 1723.48

Answer:
solution
Step-by-step explanation
P = Rs. 1435
R = 5 %
T = 3 years and 9 months
First the compound interest for 3 years will be calculated and then the amount after 3 years will be considered as principal and on this principal the simple interest for 9 months will be calculated.
Compound interest for 3 years -

⇒ 1435*21/20*21/20*21/20
⇒ 13289535/8000
= Rs. 1661.19
Now for the next 9 months the principal will be Rs. 1661.19
Simple Interest = (P*R*T)/100
⇒ (1661.19*5*9)/(12*100)
⇒ 74753.55/1200
S.I. = Rs. 62.29
Amount = P + I
A = 1661.19 + 62.29
= Rs. 1723.48
So, amount at maturity will be Rs. 1723.48
