Question

Find our simple interest and compound interest on Rs. 65000 at the rate of 12.5 annum for a 3 years 6 month​

Answer 1

Step-by-step explanation:

For first year

P=6500,R=5%, T=1

Interest =

100

PRT

=

100

(6500×5×1)

=325

Amount = Interest + Principle =325+6500=Rs.6825

For second year principle will be amount of previous year (since interest is compounded)

P=6825,R=6%, T=1

Interest =

100

PRT

=

100

(6825×6×1)

=Rs.409.5

Amount=P+I=6825+409.5=7234.5

Total interest =325+409.5=Rs.734.5

∴ Amount after 2 years will be Rs.7234.5 and interest Rs.734.5

For first year

For first yearP=6500,R=5%, T=1

For first yearP=6500,R=5%, T=1Interest =

For first yearP=6500,R=5%, T=1Interest = 100

For first yearP=6500,R=5%, T=1Interest = 100PPR

=

= 100

= 100(6500×5×1)

= 100(6500×5×1) =325

= 100(6500×5×1) =325 Amount = Interest + Principle =325+6500=Rs.6825

= 100(6500×5×1) =325 Amount = Interest + Principle =325+6500=Rs.6825For second year principle will be amount of previous year (since interest is compounded)

= 100(6500×5×1) =325 Amount = Interest + Principle =325+6500=Rs.6825For second year principle will be amount of previous year (since interest is compounded)P=6825,R=6%, T=1

= 100(6500×5×1) =325 Amount = Interest + Principle =325+6500=Rs.6825For second year principle will be amount of previous year (since interest is compounded)P=6825,R=6%, T=1Interest =

= 100(6500×5×1) =325 Amount = Interest + Principle =325+6500=Rs.6825For second year principle will be amount of previous year (since interest is compounded)P=6825,R=6%, T=1Interest = 100

= 100(6500×5×1) =325 Amount = Interest + Principle =325+6500=Rs.6825For second year principle will be amount of previous year (since interest is compounded)P=6825,R=6%, T=1Interest = 100PPR

=

= 100

= 100(6825×6×1)

= 100(6825×6×1)=Rs.409.5

= 100(6825×6×1)=Rs.409.5Amount=P+I=6825+409.5=7234.5

= 100(6825×6×1)=Rs.409.5Amount=P+I=6825+409.5=7234.5Total interest =325+409.5=Rs.734.5

= 100(6825×6×1)=Rs.409.5Amount=P+I=6825+409.5=7234.5Total interest =325+409.5=Rs.734.5∴ Amount after 2 years will be Rs.7234.5 and interest Rs.734.5
