Question

In what time will the simple interest on Rs. 400 at 10% p.a. be the same as

the simple interest on Rs.1000 for 4 years at 4% p.a. ?​

Answer 1

Answer:

4 years

Step-by-step explanation:

• simple interest = (principle*rate*time)/100
• simple interest = ( 1000*4*4)/100 = 160
• According to question, this is the same interest when principle and rate are 400 and 10 % respectivily .
• so let time is Y years.
• then (400*10*Y)/100 = 160
• so Y = 160/40 = 4 years
