Answer 2

$\large{\underline{\red{\rm{AnswEr:Rs.16}}}}$

$\huge\bold\purple{\underline{Solution:}}$

$\bold\orange{\underline{Calculation\:for\:SI:}}$

$\bold\green{\underline{Given:}}$

• Principal=Rs.10000
• Time=2 years
• Rate=4%

Using formula here for SI

$\bold\purple{\boxed{SI=\frac{P*T*R}{100}}}$

⟹SI=10000×2×4/100

⟹SI=100×2×4

⟹SI=800

$\bold\green{\underline{Calculation\:for\:CI:}}$

• Principal=Rs.10000
• Time(n)=2 years
• Rate=4%

Using formula here for CI

$\bold\purple{\boxed{CI=P(1+\frac{r}{100})^n-P}}$

⟹CI=10000(1+4/100)²-10000

⟹CI=10000(104/100)²-10000

⟹CI=10000×104/100×104/100-10000

⟹CI=104×104-10000

⟹CI=10816-10000

⟹CI=816

Now, difference between CI and SI

⟹CI-SI

⟹816-800

⟹16

Hence,

The difference between SI and CI is Rs.16
