GIVE ANSWER PLEASE​

Answer 1

Step-by-step explanation:

Amt =pricipal(1+i)^n

(a)=1200(1+0.12)^3

= 1200×1.404928

=1685.9136

(b) =7500(1+0.05)^3

=7500×1.157625

=8682.1875

Answer 2

For part A refer the attachment above ⚡

Part B

Answer:-

₹ 8625

Step-by-step explanation:-

P = ₹7500

R = 5%

T = 3 years

$\sf{ S.I. = \dfrac{ = P \times R \times T}{100}}$

$\sf{S.I. = \dfrac{7500 \times 5 \times 3}{100} }$

$\sf{S.I. = \dfrac{75 \cancel{00} \times 5 \times 3}{ \cancel{100}}}$

$\sf{S.I. = 75 \times 5 \times 3}$

S.I. = ₹1125

Now, for finding Amount,

A = P + I

A = 7500 + 1125

A = ₹8625

Therefore, Amount paid at the end of 3rd year = ₹8625

Here,

P = Principal

R = Rate

T = Time

S.I. = Simple interest

A = Amount
