Answer 1

$\bf{\Huge{\boxed{\rm{\red{ANSWER\::}}}}}$

$\bf{\Large{\boxed{\tt{First\:Case\::}}}}$

$\bf{Given}\begin{cases}\rm{Principal,[P]\:=\:Rs.5000}\\ \rm{Rate,[R]\:=\:4\%}\\ \rm{Time,[n]\:=\:1\:years}\end{cases}}$

We know that formula of the Simple Interest:

$\leadsto\sf{\purple{Simple\:Interest\:(S.I.)\:=\:\frac{P*R*T}{100} }}$

Therefore,

$\longmapsto\sf{S.I.\:=\:\frac{5000*4*1}{100} }$

$\longmapsto\sf{S.I.\:=\:\frac{50\cancel{00}*4*1}{\cancel{100}} }$

$\longmapsto\sf{S.I.\:=\:Rs.(50*4*1)}$

$\longmapsto\sf{\red{S.I.\:=\:Rs.200}}$

$\bf{\Large{\boxed{\tt{Second\:Case\::}}}}$

$\bf{Given}\begin{cases}\rm{Principal,[P]\:=\:Rs.5000}\\ \rm{Rate,[R]\:=\:7.4\%}\\ \rm{Time,[n]\:=\:1\:years}\end{cases}}$

So,

$\longmapsto\sf{S.I.\:=\:\frac{5000*7.4*1}{100} }$

$\longmapsto\sf{S.I.\:=\:\frac{50\cancel{00}*7.4*1}{\cancel{100}} }$

$\longmapsto\sf{S.I.\:=\:Rs.(50*7.4*1)}$

$\longmapsto\sf{\red{S.I.\:=\:Rs.370}}$

Now,

Difference of bank loan & agriculture loan in a Interest, we get;

$\longmapsto{\sf{Difference\:=\:Rs.(370\:-\:200)}}$

$\longmapsto{\sf{\red{Difference\:=\:Rs.170}}}$

Thus,

$\bf{\Large{\boxed{\it{The\:money\:as\:saved\:to\:be\:Interest\:per\:annum\:is\:\:\:Rs.170}}}}}$

Answer 2

Answer:$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

When farmer takes loan from agricultural society:

P = Rs. 5000, r = 4, t = 1 and I = ?

As we know,

Interest 》PRT/100

Interest 》 5000×4×1/100

Interest 》Rs.200

⇒ I = Rs. 200

When a farmer takes loan from the bank:

P = Rs. 5000, r = 7.4, t = 1 and I = ?

As we know,

Interest 》PRT/100

Interest 》 5000×7.4×1/100

Interest 》Rs.370

Hence, the money saved by farmer

= Interest(when loan is taken from bank) – Interest(from agricultural society)

⇒ 370 – 200 = Rs. 170

Hence, money saved by farmer = Rs. 270
