Scheme A offers R% p.a. rate of interest on compound annually.

Find the value of R.

Statement I – If interest received on Rs. (2/5)?? on simple interest for 11 years at the rate of ??/4% p.a. is half of when Rs. P invested in scheme A for 2 years.

Statement II – Rs. X is invested in scheme A for two years and it amounted Rs. 3600. If Rs. (16/25)?? is invested at rate of (R – 10) % on CI annually for two years, then it amounted Rs. 1936.

Statement III- When Rs. Q invested in scheme A for two years and three years, then difference between interests is Rs. 1152.

Statement (I) alone is sufficient answer the question

Statement (II) alone is sufficient to answer the question

All the three statements taken together are necessary to answer the question

Either statement (I) alone or statement (II) and (III) together sufficient to answer the question.

Either statement (I) alone or statement (II) alone is sufficient to answer the question.

Explanation:

From I –

So, From I we can get the value of R

From II –

From equ. (i) and (ii), we can get the value of R.

From III – From III we can get two variables first Amount ‘Q’ and second Rate of interest ‘R’. So, we can’t determine the value of two variables from one equation.

So, either statement (I) or statement (II) alone is sufficient to answer the question
