Question

principal is x rate of interest 3.5 % time period 2 years simple interest is x and amount is rupees 535 then find the principal and simple interest

Answer 1

Answer:

Step-by-step explanation:

Given R = 3.5%, T = 2 years

Amount = Rs 535

Recall A = P(1+TR/100)

⇒ 535 = P[1+ (2× 3.5)/100]

⇒ 535 = P[107/100]

⇒ P = 535 × (100/107) = 500

Hence principal P = Rs 500

Simple interest, I = (PTR)/100

= (500 × 2 × 3.5)/100

= (5 × 2 × 3.5) = 35

Hence interest = Rs 35

Answer 2

Answer:

Step-by-step explanation:

Given R = 3.5%, T = 2 years

Amount = Rs 535

A = P(1+TR/100)

⇒ 535 = P[1+ (2× 3.5)/100]

⇒ 535 = P[107/100]

⇒ P = 535 × (100/107) = 500

Hence principal P = Rs 500

Simple interest, I = (PTR)/100

= (500 × 2 × 3.5)/100

= (5 × 2 × 3.5) = 35

Hence interest = Rs 35
