Question:
The difference between CI and SI for 3 years at the rate of 20% p.a. is \(\unicode{x20B9} \)1600. What is the principal lent?
Options:
A) 12000
B) 11550
C) 12500
D) 13750
E) None of these
Solution:
Difference between CI and SI for 3 years =Rs.1600  

P \(\left ( \cfrac {r}{100} \right )^2 \left ( \cfrac {r}{100}+3 \right )=1600\)

P \(\left ( \cfrac {1}{25} \right )\left ( \cfrac {16}{5} \right )\) =1600


P = \(\cfrac{25×5×1600}{16}\)

= 125,00
