Question

The different between SI and CI on a certain sum of money two years at 15% p.a. is ₹144. Find the sum

Answer 1

Answer:

Rs.6400

Step-by-step explanation:

r = 15%

d = 144

=> 144 = p (r/100)²

=> 144 = p(15/100)²

=> (144*10000)/225 = p

=> (144*400)/9 = p

=> (16*400) = p

=>6400 = p

so, the principal is Rs.6400
