Question

pls answer this maths question ​

Answer 1

Answer:

3450

Step-by-step explanation:

Interest=450

Rate=5%

Time=3years

Principle=?

Principle=(Interest×100)/(Rate×Time)

=(450×100)/(5×3)

=

15

45000

=3000

therefore

sum paid after 3 years=3000+450=3450

Answer 2

Given :-

• Time (T) = 3 y
• Simple interest (SI) = Rs. 450
• Rate (R) = 5 %

To Find :-

Sum

Solution :-

We know that

[SI = PRT/100]

⇒ 450 = P × 5 × 3/100

⇒ 450 = 15P/100

⇒ 450 = 3P/20

⇒ 450 × 20/3 = P

⇒ 9000/3 = P

⇒ 3000 = P
Therefore, the sum is Rs. 3000
