Answer:
Step-by-step explanation:
Formula for CI is A-P So first we will calculate the amount,
Let the Pricipal be x. We can calculate using formula A=P(1+(r/100))^n where n is the duration of time or time,
A=P(1+5/100)^2,
A=441P/400;
CI=441P/400 - P,
=41P/400 ATQ, 41P/100,
=1640P.
=( 1640*400)/41 P,
=16000
Hence,the sum is 16000.
Hope it helps.

Step-by-step explanation:
Rate (R) = 5℅
Number of years (N) = 2
Amount (A) = 1640 Rs
To find-:
Sum or principal (P) = ?
A = P (1+R/100)^N
1640 = P ( 1+5/100)²
1640 = P ( 1+ 1/20)²
1640 = P(21/20)²
1640 =P × 21/20 × 21/20
1640 × 20 × 20/21 × 21 = P
1640 × 400/441 = P
656000/441 = P
1487.52 = P
Principal = Rs 1487.52
