Question

Find the intrest and amount on p=Rs18500 T=2 years 2months and R=5% per annum

Answer 1

━━━━━━━━━━━━━━━━━━━━

✺Answer:

♦️GiveN:

• Principal = Rs.18500
• Time = 2 years 2 months
• Rate of Interest = 5% per annum

♦️To FinD:

• Find interest and amount.....?

━━━━━━━━━━━━━━━━━━━━

✺Concept used:

The above question is just " Apply formula and get solution" type question. No general explanation needed. So, we just need to know the formula to be used.

♠️Formula for Simple Interest(S.I)

$\large{ \odot\: \: { \boxed{ \rm{ \purple{ \: S.I= \frac{ \: \: P \times T \times R}{100}}}}}}$

♦️Note:

Symbols have their usual meanings.

♠️Formula for Amount

$\large{ \odot\: \: { \boxed{ \rm{ \purple{Amount = S.I + Principal}}}}}$

Now, just applying formula we can get our required result.

━━━━━━━━━━━━━━━━━━━━

✺Solution:

Principal = Rs. 18500

Time = 2 years 2 months

= 2 1/6 years

= 13/2 years

Rate = 5 %

By Applying the above formula ,

$\large{ \rm{ \rightarrow \: S.I = \frac{P \times T \times R}{100}}} \\ \\ \large{ \rm{ \rightarrow \: S.I = \frac{185 \cancel{00} \times \frac{13}{2} \times 5 }{ \cancel{100}}}} \\ \\ \large{ \rm{ \rightarrow \: S.I = \frac{185 \times 13 \times 5}{2} }} \\ \\ \large{ \rightarrow \boxed{ \rm{ \red{ \: S.I= Rs. \: 6012.5}}}}$

▶️ So Simple Interest = Rs. 6012.50

━━━━━━━━━━━━━━━━━━━━

Now, finding the amount

By using above formula,

$\large{ \rm{ \rightarrow \: Amount = 18500 + 6012.5}} \\ \\\large{ \rightarrow \: \boxed{ \rm{ \red{Amount =Rs. 24512.50}}}}$

▶️ So Amount = Rs. 24512.50

Answer 2

Answer:

A = 1687476.27

I = 1668976.27

Step-by-step explanation:

P = 18,500

n = 2 + 2/12 = 2 + 1/6

R = 5%

CI = P(1 + R/100)ⁿ

CI = 18500 (1 + 5/100)²

    = 18500(1 + 1/25)²

    = 18500(25/25 + 1/25)²

    = 18500(26/25)²

    = 18500 × 26/25 × 26/25

A    = 20009.6

A = P

SI = PRT/100

   = 20009.6 × 5 × 1/6 × 100

   = 1667466.67

A = 20009.6 + 1667466.67

A = 1687476.27

I = 1687476.27 - 18,500

I = 1668976.27
