Answer 1

Appropriate Question :

Q2) What is the simple interest, when P=Rs 8600, T=2 years and R= 8 % p.a. ?

a) Rs 1376

b) Rs 1736

c) Rs 1637

d) Rs 1763

Given :

• Principal = Rs. 8,600
• Time = 2 years
• Rate = 8%

To find :

• Simple Interest

Knowledge Required :-

→ Formula to calculate simple Interest :-

$\star \quad \underline{\boxed{ \sf \pmb{ \red{Simple \: \: Interest = \dfrac{P \times R \times T }{100} }}}}$

where,

• P = Principal
• R = Rate
• T = Time

Solution :

Simple Interest :-

$\\ \longmapsto \quad\sf{ Simple \: \: Interest = \dfrac{P \times R \times T }{100} }$

$\\ \longmapsto \quad\sf{ Simple \: \: Interest = \dfrac{8600 \times 8 \times 2 }{100} }$

$\\ \longmapsto \quad\sf{ Simple \: \: Interest = \dfrac{86 \not0 \not0 \times 8 \times 2 }{1 \not0 \not0} }$

$\\ \longmapsto \quad\sf{ Simple \: \: Interest = \dfrac{86 \times 8 \times 2 }{1} }$

$\\ \longmapsto \quad\sf{ Simple \: \: Interest = 86 \times 8 \times 2 }$

$\\ \longmapsto \quad\sf{ Simple \: \: Interest = 1376 }$

Know MorE :-

→ Formula to calculate amount, when Principal, time and rate is given.

• Amount = P[1 + r/100]ⁿ

→ Formula to calculate compound interest, when Principal and Amount is given.

• Compound Interest = Amount - Principal

→ Formula to calculate compount interest, when Principal, rate and time is given.

• Compount Interest = P[1 + r/100]ⁿ - P

→ Formula to calculate amount, when Principal and simple interest is given.

• Amount = Principal + Simple Interest

Answer 2

Question :

What is the simple interest, when P=Rs 8600, T=2 years and R= 8 % p.a. ?

a) Rs 1376

b) Rs 1736

c) Rs 1637

d) Rs 1763

Given :

• Principal (P) = Rs 8600
• Time (T) = 2 years
• Rate (R) = 8% p.a

To Find :

• Simple Interest

Solution :

⟹ Simple Interest = P × R × T / 100

⟹ Simple Interest = 8600 × 8 × 2 / 100

⟹ Simple Interest = 86 × 8 × 2

⟹ Simple Interest = 86 × 16

⟹ Simple Interest = Rs 1376

Thus Simple Interest is Rs 1376 (Option a)
