Let x be the initial investment in A and y be the initial investment in B.

Let r be the rate of interest for A and s be the rate of interest for B.

Let n be the number of years.

Question Stem : s = (3/2)*r ; x = ?

Money in A = x + r*x*n

Money in B = y + S*y*n

St. (1) : n = 1 ; r*x = 50 ; s*y = 150

Since s = (3/2)*r ;

s*y = 150 ;

(3/2)*r*y = 150 ;

r*y = 100 ; Also, r*x = 50

Combining these two, we get : y = 2x

This does not give us the value of x.

Thus, Insufficient.

St. (2) : y = 2x

This is the same as the previous statement.

Thus, Insufficient.

St. (1) and (2) together :

Since both statements are the same, taken together they will not give us anything extra.

Thus, Insufficient.

Answer : E
