Answers

S11. Ans.(c)

Sol. In 1980-81 is 105 while in 84-85 is 151. 

So percentage increases is ((151-105)/105)×100=(46/105)×100=43% 

S12. Ans.(d)

Sol. Total requirement = 120 + 129 + 137 + 145 + 170 = 701

Total supply = 105 + 115 + 124 + 130 + 151 = 625 

Difference = 701 - 625 = 76 

S13. Ans.(b)

Sol. 170 = 97 × x 

So, x=170/97=1.75   

S14. Ans.(d)

Sol. % Growth =(170-118)/118×100=44% 

In 1974-75 to 1979-80 growth =(118-78)/78=40/78×100=51% 

So, more = 51 - 44 = 7% 

S15. Ans.(c)

Sol. In 1979-80 demand was 118 which completed in 82-83 means 3 years
