Question

Which is the rate of interest for rupees 2500 at simple interest to become rupees 3300 in 4yrs ​

Answer 1

Answer: Rate% = 8%

Step-by-step explanation:-

Amount = ₹3300

Principal = ₹2500

Time = ₹4 years

Amount(A) =Principal

(P)+Simple Interest (S.I.)

A = P + (PRT/100)

A = P{1+ (RT/100)}

₹3300= 2500{1+(R x 4/100)}

₹3300/2500= (25+R)/25

₹33/25*25 = 25 + R

Then,cancel 25 with 25

R = ₹(33-25)

R = 8%
