Answer 1

$\huge\boxed{\underbrace{\mathfrak{\pink{\fcolorbox{yellow}{black}{Answer☘}}}}}$

Principle amount = 2000

Rate of interest =5%

Number of years = 2

NEED TO FIND

Compound interest=?

Amount=?

${\huge{\underline{\large{\mathbb{\purple{FORMULA\:USED:)}}}}}}$

A=P(1+r/n)nt

A=2000(1+5/2)2×1

A=2000(4/2)2

A=2000×2×2

A=4000×2

A=8000

Interest=principle Amount - Amount

Interest= 2000-8000

Interest = 4000

Answer 2

Answer:

Amount = Rs. 8000 and Interest = Rs. 4000

Step-by-step explanation:

Given:-

Principle = Rs. 2000  

Rate of interest = 5% p.c.p.a  

Number of years = 2  

To Find:

Compound interest and amount

Solution:

To Find amount, the formula is:

$A=P(1+r/n)nt$

  $A=2000(1+5/2)2*1A=2000(4/2)2A=2000*2*2A=4000*2A=8000$

To find intrest, the formula is:

$Interest = Amount - Principal$

$Interest = 8000-2000$

$Interest = 4000$

∴ The Amount = Rs. 8000 and Interest = Rs.4000

HOPE IT HELPS!! PLZ MARK ME AS BRAINLIEST :)

NOTE:- TO VERIFY YOUR ANSWER, THE PRINCIPAL CANNOT BE MORE THAN THE AMOUNT!
