यदि मूल राशि = रु. S, ब्याज दर = 2r % प्रतिवर्ष, तो व्यक्ति को 3 वर्ष के बाद चक्रवृद्धि ब्याज पर कितनी राशि मिलेगी ?

Options

A. `₹ (6Sr)/(100)`
B. `₹ S(1+(r)/(50))^(3)`
C. `₹ S(1+(r)/(100))^(3)`
D. `₹ 3S(1+(r)/(100))^(3)`

Answer

b

Explanation

(b) According to the question
Principal = Rs. S
Rate = 2 r% p.a
Time = 3 years.
`therefore A = P (1 + (R)/(100))^(T)`
`A = S (1 + (2r)/(100))^(3)`
`A =S (1 +(r)/(50))^(3)`
