1) Minimum return will be gained if the extraordinarily performing stocks(double and 1.5 growth) are the ones whose expected returns are lowest (10% and 20%). Taking the minimum value of the expected returns as 10. We have to see which of the two values of 10 and 20 multiplied with 2 and 1.5 and viceversa yield the minimum value.
Now, compare the minimum value between 20×2+10×1.5 and 10×2+20×1.
Minimum average return is
2) If the average return is 35%, then the total return is 35*4 = 140
Possible arrangements of 140 are
(i) 40×1.5+30+20×2+10
A = 20×2(Cement or IT)
B = 10, C = 30
D = 40×1.5 (Steel or Auto)
or
(ii) 40 + 30×2 + 20×1.5 + 10
A = 20×1.5(Steel or Auto)
B = 10, C = 30×2(Cement or IT)
D = 40
Hence, Statements ii and iii are correct.
3) If the average return is 35%, then the total return is 38.75*4 = 155
Possible arrangements of 155 is
20 + 10 + 30×1.5 + 40×2
A = 20, B = 10
C = 30(Steel or Auto)
D = 40(Cement or IT)
Hence, Statements i and iv are correct.
Analytical Reasoning Set 1
Venkat, a stockbroker, invested a part of his money in the stock of four companies  A, B, C and D.
Each of these companies belonged to different industries, viz., Cement, Information Technology (IT), Auto and Steel, in no particular order.
At the time of investment, the price of each stock was Rs 100. Venkat purchased only one stock of each of these companies. He was expecting
returns of 20%, 10%, 30% and 40% from the stocks of companies A, B, C and D, respectively. Returns are defined as the change in the value
of the stock after one year, expressed as a percentage of the initial value. During the year, two of these companies announced extraordinarily
good results. One of these two companies belonged to the Cement or the IT industry, while the other one belonged to either the Steel
or the Auto industry. As a result, the returns on the stocks of these two companies were higher than the initially expected returns.
For the comapnies belonging to the Cement or the IT industry with extraordinarily good results, the returns were twice that of the
intially expected returns. For the comapnies belonging to the Steel or the Auto industry, the returns on the announcement of
extraordinarily good results were only one and a half times that of the intially expected returns. For the remaining two companies
which did not announce extraordinarilygood results, the returns realized during the year were the same as initially expected.

SOLUTIONS:
1) Minimum return will be gained if the extraordinarily performing stocks(double and 1.5 growth) are the ones whose expected returns are lowest (10% and 20%). Taking the minimum value of the expected returns as 10. We have to see which of the two values of 10 and 20 multiplied with 2 and 1.5 and viceversa yield the minimum value.
Now, compare the minimum value between 20×2+10×1.5 and 10×2+20×1.
Minimum average return is
2) If the average return is 35%, then the total return is 35*4 = 140
Possible arrangements of 140 are
(i) 40×1.5+30+20×2+10
A = 20×2(Cement or IT)
B = 10, C = 30
D = 40×1.5 (Steel or Auto)
or
(ii) 40 + 30×2 + 20×1.5 + 10
A = 20×1.5(Steel or Auto)
B = 10, C = 30×2(Cement or IT)
D = 40
Hence, Statements ii and iii are correct.
3) If the average return is 35%, then the total return is 38.75*4 = 155
Possible arrangements of 155 is
20 + 10 + 30×1.5 + 40×2
A = 20, B = 10
C = 30(Steel or Auto)
D = 40(Cement or IT)
Hence, Statements i and iv are correct.
