Question

If the difference betweet CI and SI on a
certain sum for 2 years at 10% per annum
compounded annually is Rs 50 find the sum​

Answer 1

Step-by-step explanation:

ANSWER

SI=100PRT=100P×10×2=5P=0.2P

CI=A−P

=P(1+r)t−P

=P((1+0.1)2−1)

=P((1.1)2−12)

=P(1.1+1)(1.1−1)

=P(2.1)(0.1)

=0.21P

CI−SI=0.21P−0.2P=50

=0.01P=50

=P=0.0150×100=5000Rs.

hope this helps you mate!!!!!

Simple Interest = PRT/100

= P × 10 × 2 /100

= P/5

= 0.2P

CI =A−P

= P( 1 + r )t − P

= P(( 1 +0.1 )2 −1 )

= P( (1.1 )2 − 12 )

= P( 1.1 + 1 )( 1.1 − 1 )

= P( 2.1 )( 0.1 )

= 0.21P

CI − SI = 0.21P − 0.2P = 50

=> 0.01P = 50

=> P = 50×100/0.01

=> ₹5000.
