Question

Find the simple interest on 55,000 for 3 years, when the rate of interest is 12% p.a.​

Answer 1

Answer:

Given :-

• A sum of Rs 55000 for 3 years, when the rate of interest is 12% per annum.

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 = Rs 55000
• Rate of Interest = 12% per annum
• Time = 3 years

According to the question by using the formula we get,

⇒ $\sf S.I =\: \dfrac{55000 \times 12 \times 3}{100}$

⇒ $\sf S.I =\: \dfrac{1980000}{100}$

⇒ $\sf S.I =\: \dfrac{\cancel{1980000}}{\cancel{100}}$

➠ $\sf\small\bf{\underbrace{\red{S.I =\: Rs\: 19800}}}$

$\therefore$ The simple interest on Rs 55000 for 3 years is Rs 19800 .

Answer 2

Question :-

• Find the simple interest on 55,000 for 3 years, when the rate of interest is 12% p.a.

Given :-

• Principal = 55,000
• Rate = 12%
• Time = 3 years

To Find :-

• What is the Simple Interest ?

Solution :-

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

${:} \longrightarrow \sf{\sf{Simple \: Interest \: = \: \dfrac{55000 \: \times \: 12\: \times\: 3}{100} }}$

${:} \longrightarrow \sf{\sf{Simple \: Interest \: = \: \dfrac{550\cancel{00} \: \times \: 12\: \times\: 3}{1\cancel{00}} }}$

${:} \longrightarrow \sf{\sf{Simple \: Interest \: = \: 550 \: \times \: 12\: \times\:3 }}$

${:} \longrightarrow \sf{\bf{Simple \: Interest \: = \: Rs, 19800 }}$

━━━━━━━━━━━━

Verification :-

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

$\longmapsto \sf{\sf{19800 \: = \: \dfrac{55000 \: \times \: 12\: \times\: 3}{100} }}$

$\longmapsto \sf{\sf{19800 \: = \: \dfrac{550\cancel{00} \: \times \: 12\: \times\: 3}{1\cancel{00}} }}$

$\longmapsto \sf{\sf{19800 \: = \: 550 \: \times \: 12\: \times\:3 }}$

$\longmapsto \sf{\bf{19800 \: = \: 19800 }}$

━━━━━━━━━━━━

∴ Simple Interest = Rs, 19800
