Answer:
Option C
Explanation:
I. gives : P = Rs. 1000 and S.I for 1 year = Rs. 100.
∴ Rate =100×S.I.P×T
=100×1001000×1 =10% p.a.
Thus, P = Rs. 1000,T=3 years and R=10 p.a.
∴ C.I. may be obtained.
II. Sum = Rs. 1000,(C.I.)−(S.I.) for 2 years = Rs. 10.
Let the rate be R% p.a.
1000×[(1+R100)2−1] −(1000×R×2100) =10.
From this, we can find R.
Thus P, T and R are given and therefore, C.I may be calculated.
Thus, I alone as well as II alone is sufficient to get the answer.
∴ Correct answer is (C).
