Question

IN WHAT TIME RS 2560000 YIELDS AMOUNT WILL BE RS858801 COMPOUNDED at the rate of 15% p.a compounded harfly yearly.find it​

Answer 1

Answer:

: Principal for the first year =Rs 1000

SI\quad =\frac { P\times R\times T }{ 100 } \\ SI\quad for\quad 1st\quad year\quad =\frac { 1000\times 4\times 1 }{ 100 } \\ SI\quad for\quad 1st\quad year\quad =Rs\quad 40

SI=

100

P×R×T

SIfor1styear=

100

1000×4×1

SIfor1styear=Rs40

Amount at the end of first year =Rs1000 + Rs 40 = Rs 1040. Principal for the second year = Rs1040

SI\quad for\quad 2nd\quad year\quad =\frac { 1040\times 4\times 1 }{ 100 }

SIfor2ndyear=

100

1040×4×1

SI\quad for\quad 2nd\quad year\quad =Rs\quad 41.60

SIfor2ndyear=Rs41.60

Amount at the end of second year,

Amount=Rs1040+Rs41.60=Rs1081.60

Amount=Rs1040+Rs41.60=Rs1081.60

Therefore,

Compound\quad interest=Rs(1081.60–1000)=Rs81.60

Compoundinterest=Rs(1081.60–1000)=Rs81.60

Answer 2

R15%pa =7.5%half yearly
P= ₹2560000
A=₹858801 how amount can be less than principal
