Answer 1

Explanation:

SI = rupees 280

Principal = rupees 56000

Time = 2 years

Rate = ?

Solution =

SI = P× R × T/ 100

Rupees 280 = 56000×R×2/100

Rupees 280 = 560× 2x

2x = 280/560

2x 1/2

X = 1/2÷2/1

= 1/2×1/2

Rate= 0.25

Answer 2

Answer:

(1). 0.25 %

The rate is 0.25 %

Explanation:

Given:

Principal (P) : Rs 56,000

Simple Interest (SI) : Rs 280

Time (T) : 2 years

To find :

Rate (R)

Solution :

SI = P × R × T / 100

⇒ 280 = 56,000 × R × 2 / 100

⇒ 280 = 560 × R × 2

⇒ 280 = 1,120 R

⇒ R = 280 / 1,120

⇒ R = 0.25

Therefore,

(1). 0.25 %

The rate is 0.25 %
