Rs 1200 then find the sum?
(a) Rs 25,000
(b) Rs 36,000
(c) Rs 35,000
(d) Rs 24,000
(e) Rs 30,000

Answer 1

Rs 5000

Step-by-step explanation:

Compound interest for 1st year

20 A=P(1 100) 1+

I=A-P

1₁-1(1+200) - P =

Compound interest for 2nd year 2 1₂ = P(1 + 20 )³² - P

100

difference = 1200

1200 = P(1 + 200 ) P1+ ³² - P- P(1 + 200 ) + P

1200-P(1+200)-(1+200)

0= P(1 + 2006) ((1+ 200 ) - 1)

1200

1200 = Px 120 20 X 100 100

P = 5000
