Answer 2

ɢɪᴠᴇɴ :-

• Principal (P) = 150
• Rate (R) = 5%
• Time (T) = 4 years

Tᴏ ғɪɴᴅ :-

• Simple Interest (SI)
• Amount (A)

sᴏʟᴜᴛɪᴏɴ :-

We know that,

$\implies \tt \: Simple \: Interest \: (SI) = \frac{Principal(P) \times Rate(R) \times Time(T)}{100} \\ \\ \\ \implies \tt \: SI = \frac{PRT}{100}$

Put the above given values in it, we get,

$\implies \sf \: SI \: = \frac{150 \times 5 \times 4}{100} \\ \\ \\ \implies \sf \:SI = \frac{3000}{100} \\ \\ \\ \implies \sf \: SI = 30$

We get,

➦ Simple Interest (SI) = 30

Now,

We know that,

Amount (A) = Principal(P) + Interest(I)

➦ A = P + I

We get,

➮ A = 150 + 30

➮ A = 180

Hence,

• Simple Interest (SI) = 30
• Amount(A) = 180
