Question

In what time will Rs. 1860 amount to Rs. 2278.50, if simple interest is calculated at 9% per annum?​

Answer 1

Answer:

2.5 years

Step-by-step explanation:

SIMPLE INTEREST= Amount-Principal= 2278.50-1860= 418.5

Simple interest= (P*R*T)/100

we already know the principal and the rate of interest

and the simple Interest

So,

(1860*9*T)/100=418.5

1860*9*T=41850

T*9= 41850/1860=22.5

T=22.5/9=2.5

Answer 2

Given :-

• Principal = Rs.1860

• Amount = 2278.50

• Rate of interest = 9%

Solution :-

Here,

Amount and Principal is given

Then ,

As we know that,

SI = Amount - Principal

[ Amount = 2278.50 , Principal = 1860 ]

Put the required values in the formula,

SI = 2278.50 - 1860

SI = 418.5

Hence, Simple Interest is Rs. 418.5

According to the question ,

Now, we have to find the time?

Therefore,

By using formula to calculate SI

SI = P * R * T / 100

Put the required values,

418.5 = 1860 * 9 * T / 100

418.5 * 100 = 1860 * 9 * T

41850 = 16740 * T

T = 41850/16740

T = 2.5

Hence,

Time required = 2.5 years $.$
