## Re: JNU 2012 Answer Key

 Hi Viv.. In Q. 91, If I am not wrong, we need to determine the tax rate that implements purchase of exactly two cows. And according to you, when n=2, new TR-TC = 14-2t. By putting different values of 't' from the options, I found that option (c) i.e t=0 maximizes the aggregate income, and not t=6. Please help. I'm stuck :(

 76 Growth of Real GDP 1975-80, 21-17/17= 0.2352 1980-85, 26-21/21= 0.2380 1985-90, 32-26/26= 0.2307 1990-95,39-32/32= 0.2187 So Highest is in 1980-85. 77 Lowest is in 1990-95 refer last calculations 78 First solve Growth of Nominal GDP 1975-80, 26-21/21= 0.2380 1980-85, 32-26/26= 0.2307 1985-90, 39-32/32= 0.2187 1990-95, 47-39/39= 0.2051 GDP Deflator = (Nominal GDP/Real GDP)*100 1975-80, (0.2380/0.2352)*100 = 101.19 1980-85, (0.2307/0.2380)*100 = 96.93 1985-90, (0.2187/0.2307)*100 = 94.79 1990-95, (0.2051/0.2187)*100 = 93.78 So in 3 periods economy experienced Deflation 79 In 1 period economy experienced Inflation If possible then plz explain Q44 and Q45

 i approached q44-45 this way- we are given that both the statements of person in hockey team are true, in soccer team are false & in cricket team one true & another false. first consider B; assume B is in the soccer team(means both of his statements are false). From this we know 1) B is actually in the soccer team, & 2) D is not in the cricket team.( D must be in the hockey team) so, 44) bnow consider each of the options for 45).
