Question

principal = rupees 500 simple interest = rupees 150 and time = 4 years .
​

Answer 1

Answer:

Given :-

Principal = ₹500

Simple Interest = ₹150

Time = 4 years

To Find :-

Rate

Solution :-

As we know that

✠ SI = Principal×Time×Rate/100

⟹ 150 = 500×4×R/100

⟹ 150 = 5 × 4 × R

⟹ 150 = 20R

⟹ R = 150/20

⟹ Rate = 7.5 years

Answer 2

Given :-

• Principal = ₹500.

• Simple interest = ₹150.

• Time = 4 year

To Find :-

• Rate

Solution :-

We know that,

▣ Si = P × T × R/100

Values ,

$\leadsto\sf{150 = \bigg\lgroup{\cfrac{500 \times 4 \times R}{100} }\bigg\rgroup} \\ \\ \leadsto\sf{150 = \bigg\lgroup{\cfrac{2000 \times R}{100} }\bigg\rgroup} \\ \\ \leadsto\sf{150 = 20 \times R} \\ \\ \leadsto\sf{R = \cfrac{150}{20} } \\ \\ \leadsto{\boxed{\frak{\color{green}{R = 7.5}}}}$

Therefore, Rate = 7.5
