Q:

In these questions, a relationship between different elements is shown in the statements. The statements are followed by two conclusions.

Statements: M < S<=T = R>=D > E>=F, G<=S < H

Conclusions:

I.G = R

II.G < R

A) Only conclusion I is true. B) Only conclusion II is true.
C) Either conclusion I or II is true. D) Neither conclusion I nor II is true.
 
Answer & Explanation Answer: C) Either conclusion I or II is true.

Explanation:

Given:M < S<=T = R>=D > E>=F ...(i)

G<=S < H ...(ii)

Combining (i) and (ii), we get

G<=S<=T = R>=D > E>F andH > S<=T = R>=D > E>=F and

G<=S > M and M < S < H

(I) G = R is not true.

(II) G < R is not true.

But both are complamentary are pair.

Question : 

What is the rate of interest per year ?

Statements :

1. The amount invested is Rs. 6000.
2. The amount becomes Rs. 6741.60 in 2 years at compound interest.
3. The difference between compound interest and simple interest in 2 years is Rs. 21.60.

A) Only 3 B) Both 2 & 3
C) Any two of (1, 2 & 3) D) None
 
Answer & Explanation Answer: C) Any two of (1, 2 & 3)

Explanation:

Using Both 1 & 2 statements we get the rate of interest as in (1) we have given principle amount and in (2) compound interest for 2 years. By this data we get the rate%.

Using Both 1 & 3 statements we can get the rate% as we have principle amount & difference between compound interest and simple interest in 2 years.

Using Both 2 & 3 statements we get compound interest & simple interest by which we get principle amount. So that we can calculate %rate.

Hence by using any two of the three statements(1,2&3) we get rate of interest.
