1 .
 Answer : Option A Explanation : I alone is sufficient because area of a square=[$diagonal of the square\over\sqrt{2}$] $^2$  Since we have information regarding the diagonal of the square, it is easy to get the square. II alone is not sufficient because the circumference of the circle is not known
2 .
 Answer : Option D Explanation : We need some more information, such as the salary she was getting seven years ago
3 .
 Answer : Option C Explanation : From I:We have, 1500(1+$r\over100$)$^2$=1500+660[Where r = rate of interest per annum]1+$r\over100$= $2160\over1500$⇒1+$r\over100$=1+$20\over100$r=20%From II:Rate of interest per annum =$100\over5$=20%
4 .
 Answer : Option D Explanation : Neither of the two information s give clues regarding absolute number of employees

 Answer : Option D Explanation : Suppose the two-digit number is 10x + y.Now,From I:We have x + y = 8From II:We have x - y = 2Now,From I and II:we getx = 5 and y = 3Hence, the number is 53 (because 53 > 35
6 .
 Answer : Option B Explanation : The required average % marks=$65+75+60+70+55+60\over6$=$385\over6$=64$1\over6$Approximate average marks = 64$1\over6$%of80≈51
