Question

interest on rs.100 for 1 year is rs.10 . at the same rate how much is interest on rs.250?

Answer 1

SI = rs. 10
Amount = 100 + 10 = 110
SI = prt / 100
let the rate be x.
10 = 100 × 1 × x / 100
10 % pa = x.

Case 2.)
p = 250
r = 10 %
t = 1
SI = prt / 100
Si = 250 × 10 × 1 / 100
SI = 25rs.

Answer 2

Hey Friend,

Here's your answer,

Principal:₹100
Time:1year
Rate:?

Now, By using Simple Interest Formula, We Get

SI=PRT/100
10=100*R*1/100
10=Rate

Therefore,

The Rate of interest is 10%

Now,

For Principal, ₹250

SI=250*10/100
SI=2500/100

Therefore,

Interest Is ₹25

Hope It Helps......!!!! :-)
