Question

कितने समय में ₹350,
25 % वार्षिक ब्याज की दर से ₹385 हो जायेगा?​

Answer 1

Step-by-step explanation:

Here given

Principle p =₹ 350

amount a =₹ 385

Rate r = 25%

time t = ?

Simple interest = amount - principal

= 385-350

= ₹ 35

$interest \: = \frac{principal \times rate \times time}{100} \\ 35 = \frac{350 \times 25 \times t}{100} \\ \\ 35 = \frac{350 \times t}{4} \\ \\ t = \frac{35 \times 4}{350} \\ \\ t = 0.4 \: \: year$
