Question

Principle 400 rate of interest 9 /2 % time period 3 year 4 month find simple interest and amount

Answer 1

$<b>Heya mate. (^_-). Solution below.$
====================================

• Given Principal (P) = 400 Rs.

• Given Rate of interest (R) = 9/2%

• Given Time (T)
= 3 year 4 months
= 3 × 12 + 4 months
= 36 + 4 months
= 40 months
= 40/12 years.



• Then, Simple Interest (S.I)

= P × R × T /100

= [400 × (9/2) × (40/12) ]/100

= 400 × 9 × 40 / 2 × 12 × 100

= 144000/2400

= 60 Rs.

• So, S.I = 60 Rs.




• Now, amount (A)

= P + S.I

= 400 + 60

= 460 Rs.

• So, A = 460 Rs.

Answer 2

Answer:

Hey dear plz make me as brainlist.

Step-by-step explanation:

Your answer is here

P = ₹ 400

R = 9/2 years

Given T

= 3 years 4 months

= 3 × 12 × 4 months

= 36 + 4 months

= 40 months

= 40/12 years

SI = P× R × T / 100

= 400 × 9/2 × 4/ 12 /

100

= 144000 / 2400

Hence, ₹ 60

SI = ₹ 60

Now amount

A = P + SI

= 400 + 60

= ₹ 460
