Question

if if rupees 450 amounts to rupees 540 in 4 years at simple interest find the sum that will amount to rupees 630 7.50 is 5:00 in 5 years at the same rate of interest​

Answer 1

The sum that will amount to rupees 6307.50 in 5 years at the same rate of interest is Rs. 5046.

Step-by-step explanation:

Required Formula:

(1) S.I. = $\frac{PRT}{100}$

(2) Amount, A = P + S.I.

Case 1:

Principal, P = Rs. 450

Amount, A = Rs. 540

Time period, T = 4 years

Let the rate of interest be “R%”.

By substituting the given values in the above-required formulas, we get  

A – P = $\frac{PRT}{100}$

⇒ 540 – 450 = $\frac{450*R*4}{100}$

⇒ 90 = 9*2*R

⇒ R = 5 %

Case 2:

Amount, A = Rs. 6307.50

Time period, T = 5 years

Let the sum or principal be denoted as “P”.

Here, in this case, the rate of interest is given to be same as the previous case 1 i.e., R = 5 %

Similarly, by substituting the given values in the above formulas, we get  

A – P = $\frac{PRT}{100}$

⇒ 6307.5 – P = $\frac{P*5*5}{100}$

⇒ 25230 – 4P = P

⇒ 5P = 25230

⇒ P = $\frac{25230}{5}$

⇒ P = Rs. 5046

Thus, the sum of Rs. 5046 will amount to Rs. 6307.5 in 5 years at the rate of 5%.
