Question

If the difference between c.i. and s.i. on a certain sum of money for 3 years at 5% per annum is rs. 122. find the sum.

Answer 1

Answer:

diff.b/w Ci&sl for 3 yrs=Rs122

Rate 5%, P =?

Diff=P(r/100) 2x (3+r/100)

122=P(5/100) ^2x (3+5/100)

122=P(25/10000) x 305/100

122=PX25x305 /10000x100

P=10000x100x122/25x305

= 16000

SumP=Rs16000
