Q1. A deficit budget is one where
Answer : Option D
Explaination / Solution:
No Explaination.
Q2.
Find the median
Answer : Option D
Explaination / Solution:
In case of discrete series the position of median i.e. (N+1)/2th item can be located through cumulative frequency. The corresponding value at this position is the value of median.
Value: 20 29 30 39 44
Frequency: 2 4 4 3 2
Cumulative frequency 2 6 10 13 15
M= 15+1/2 = 8th place which is located in 30
Value: 20 29 30 39 44
Frequency: 2 4 4 3 2
Cumulative frequency 2 6 10 13 15
M= 15+1/2 = 8th place which is located in 30

Q5. A stone of mass 0.25 kg tied to the end of a string is whirled round in a circle of radius 1.5 m with a speed of 40 rev./min in a horizontal plane. What is the tension in the string?
Answer : Option A
Explaination / Solution:
Let, m=0.25 kg, r= 1.5m and f= 40 rev/min = 40 rev /60 s= 2/3 rps
Tension in the string = Centripetal force
so,
Q6. Viral infection can be treated by
Answer : Option D
Explaination / Solution:
Interferons can be sued to treat viral infection as interferon are proteins made and released by host cells in response to presence of pathogen as viruses, bacteria or tumor cells.

Q8. The equivalent resistance of two resistances P and Q which are in series is
Answer : Option C
Explaination / Solution:
Equivalent resistance of two resistances connected in series is equal to the sum of the two resistances.
Q9. A triply ionized beryllium ion , (a beryllium atom with three electrons removed), behaves very much like a hydrogen atom except that the nuclear charge is four times as great. For the hydrogen atom, the wavelength of the photon emitted in the n =2 to n=1 to transition is 122 nm. What is the wavelength of the photon emitted when a ion undergoes this transition?
Answer : Option C
