find the amount and compound interest principle =2000, rate of interest 5p.c.p.a, year =2years

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

${\Huge{\underline{\underline{\bf{\maltese Answer:-}}}}}$

principle =2000

rate =20%

time =2year 3 months = 27/24=9/8

si1=prt/100 = 2000×20×1/100=400

amount=2000+400=2400

si2=2400 ×20×1=480

compound=si1+si2

=2400+480

=2880

compound interest =400+480

= 880

480 is the answer.

hope it will help you.

Answer 2

Answer:

For the 1st year

Principal = Rs.2000

Rate = 5%

So,

→l = P × R × T = Rs.2100 × 5 × 1 = Rs.105

100 100

The amount after the second year = Rs. 2100 + Rs. 105

= Rs.2205

Final amount Rs.2205

Hence,

Compound interest Final amount— original amount

→ Rs.2205 — Rs.2000 = Rs.205

→ Rs.205
