131. In which year the annual growth rate of total production (of all products) is highest?

       (A)  1991                    (B) 1992                           (C) 1993               (D) 1995

 

         Solution:

        In the year 1992 the annual growth rate is    highest it is .

 

        In other years     in the choices the annual growth rate was lesser or else the total production decreased over the previous year                                                                                                                                                             Choice (B)

 

132. If the stability of production during 1990 to 1995 is defined as,  

 

       then which product is most stable?

       (A)  Product P                 (B) Product Q             (C) Product R             (D) Product S

 

      Solution:

        Stability =

 

        The stability is  maximum for S. Its stability is 1.63                                                                                           Choice (D)

 

133. If four products P, Q, R and S shown in the graph are sold at price of Rs.9, Rs.4, Rs.13 and Rs.3 respectively during 1990-1995, then the total revenue of all the products is lowest in which year?

       (A)  1991                         (B) 1992                      (C) 1993                     (D) None of the above

 

Solution:

 

The productions of Q and R are minimum in 1993 over the given period. The productions of P and R are not the maximum over the given period. \ It is possible that the total revenue of all the products is lowest in 1993. Working out the total revenue of P and R in each year, it is observed to be minimum in 1993. Total revenue was the lowest in 1993.                           Choice (C)

 

134. Individual revenue of P, Q, R and S for the entire period (1990 – 1995) is calculated based on the price of Rs.9, Rs.4, Rs.13 and Rs.3 respectively. Which product fetches the lowest revenue?

       (A)  Product P                 (B) Product Q       (C) Product R             (D) Product S

 

Solution:

 

        During the given period for the production of Q fetches the lowest revenue                                                           Choice (B)

 

135. Four products P, Q, R and S shown in the graph are sold at price of Rs.9, Rs.4, Rs.13 and Rs.3 respectively, during 1990-1995. Which of the following statements is TRUE?

       (A)  Product R fetches second highest revenue across products in 1991.

       (B)  Sum of revenue of P, Q and S is more than the revenue of R in 1994.

       (C)  Cumulative revenue of P and Q is more than the revenue of S in 1993.

       (D)  None of the above

 

       Solution:

        Choice A

        It is clear in the year 1991 that

        revenue from R = 92  13 = Rs 1556,

        revenue from P = 25   9 = Rs 225,

        revenue from Q = 42  4 = Rs 168 and

        revenue from S = 158 3 = Rs 574

        \ Choice A statement is false.

        In 1994,

        Sum of revenue from P, Q and S ==675+160+264 = Rs 1099

        Revenue of R = 13213 = Rs.1716

        Choice B also proves to be false

        Choice C

        Cumulative revenue from P and Q = (45+25+40+38)9+  (98+42+108+60)4

        =(148  9) + (302  4) = 1332+1208 = Rs 2540

        Revenue from S = (115+158+165+140)3 = Rs 1734

        Choice C is true                                                                                                                                            Choice (C)
