UGC NET Paper1 Previous Year Solved Papers - 5th December 2019 Morning Shift
- Option : B
- Explanation : Let ADCDEF is a cylinder with
hemispherical ends.
Diameter of the cylinder BD = 2d
height of the cylinder AD = 6d
total length = 6d + d + d = 56
8d=56
d=7cm.
Surface area of the solid
= Surface area of cylindrical parts + 2 x surface area of hemisphere
= 2π x d x 6d + 2 x 2π (d)2
= 12πd2 + 4πd2 = 16πd2
= 16 x (22/7) x 72 = 2464 cm2
- Option : A
- Explanation : Intellig~nce and motivation determine academic performance of students. Gender or physique does not affect it.
- Option : C
- Explanation :
993 = P [1.331-1]
⇒ 993 = (0.331)P
P = 993/0.331 = 3000
Now, simple interest (S.I.) = Prt/100
= (3000 x 8 x 4)/100 = 960
- Option : C
