Question

Find the simple interest on Rs1200 at the rate of 5% per annum for 73 days.​

Answer 1

Answer:

Given :-

• A sum of Rs 1200 at the rate of 5% per annum for 73 days.

To Find :-

• What is the simple interest.

Formula Used :-

${\purple{\boxed{\large{\bold{S.I =\: \dfrac{P \times R \times T}{100}}}}}}$

where,

• S.I = Simple Interest
• P = Principal
• R = Rate of Interest
• T = Time

Solution :-

Given :

• Principal (P) = Rs 1200
• Rate of Interest (R) = 5%
• Time (T) = 73 days

According to the question by using the formula we get,

⇒ $\sf S.I =\: \dfrac{1200 \times 5 \times 73}{100}$

⇒ $\sf S.I =\: \dfrac{1200 \times 365}{100}$

⇒ $\sf S.I =\: \dfrac{438000}{100}$

⇒ $\sf S.I =\: \dfrac{4380\cancel{00}}{\cancel{100}}$

➠ $\sf\bold{\red{S.I =\: Rs\: 4380}}$

$\therefore$ The simple interest is Rs 4380 .

Answer 2

Given :-

• Principal = Rs,1200
• Rate = 5%
• Time = 73days

To Find :-

• Simple Interest

Formula :-

${:} \longrightarrow \sf\boxed{\sf{Simple \: Interest \: = \: \dfrac{Principal \: \times \: Rate \: \times \: Time}{100} }}$

Solution :-

${:} \longrightarrow \sf{\sf{Simple \: Interest \: = \: \dfrac{Principal \: \times \: Rate \: \times \: Time}{100} }}\\\\{:} \longrightarrow \sf{\sf{Simple \: Interest \: = \:\dfrac{1200 \: \times \: 5 \: \times \: 73}{100} }}\\\\{:} \longrightarrow \sf{\sf{Simple \: Interest \: =\dfrac{ \: 12\cancel{00} \: \times \: 5 \: \times \: 73}{1\cancel{00}} }}\\\\ {:} \longrightarrow \sf{\sf{ Simple \: Interest \: = \: 12\: \times \: 5 \: \times \: 73 }}\\\\ {:} \longrightarrow \sf{\sf{ Simple \: Interest \: = \: 60 \: \times \: 73 }}\\\\ {:} \longrightarrow \sf{\bf{ Simple \: Interest \: = \:Rs,4200}}$

________________

So, Simple Interest is Rs,4200
