Answer 1

Question⤵️

Calculate the amount on Rs. 4000 at 10% p.a. for 2 years if compounded annually.

Answer⤵️

Given:- Principal = Rs.4000

Time = 2 years

Rate = 10%

To find:- The amount compounded annually.

Solution:-

=>Principal (P)=Rs.4000

=>Rate of Interest (R) = 10%

=>Time (T) = 2 years

$principal \: for \: the \: 1st \: year = rs.4000 \\ interest \: for \: the \: 1st \: year = rs.(4000 \times \frac{10}{100} \times 1) = rs.400 \\ amount \: at \: the \: end \: of \: 1st\: year = rs.(4000 + 400) = rs.4400. \\ hence \: principal \: for \: 2nd \: year = rs.4400 \\ interest \: for \: 2nd \: year \: = rs.(4400 \times \frac{10}{100} \times 1) = rs.440 \\ amount \: at \: the \: end \: of \: 2nd \: year = rs.(4400 + 440) = rs.4840 \\ c.i \: for \: 2 \: years = (amount) - (original \: principal) \\ = rs.(4840 - 4000) = rs.840 \\ hence \: amount = rs.4840 \: and \: c.i = rs.840.$

Answer 2

Answer:

Amt = 4,840

Step-by-step explanation:

Principle = 4,000

Rate of interest = 10%

Time = 2

Amt = p( 1 + r/100)ⁿ

Amt = 4,000( 1 + 0.10)²

Amt = 4,000(1.10)²

Amt = 4,000 * 1.21

Amt = 4,840
