Q3. The ionic reactions are generally very fast because
Answer : Option B
Explaination / Solution:
Ionic reactions does not involve bond breaking therefore they are fast.
Q4. Smooth curve joining the points corresponding to the frequency and provides frequency curve of the data
Answer : Option C
Explaination / Solution:
The frequency curve is obtained by drawing a smooth freehand curve passing through the points of the frequency polygon as closely as possible. It may not necessarily pass through all the points of the frequency polygon but it passes through them as closely as possible.

Rural population need short term loans for meeting consumption expenditure.
Rural population needs long term loan For buying agricultural machinery, land etc.
Rural population needs middle term loan for buying cattle etc.
Q6. An aircraft is flying at a height of 3400 m above the ground. If the angle subtended at a ground observation point by the aircraft positions 10.0 s apart is 30, what is the speed of the aircraft?
Answer : Option D
Explaination / Solution:
The positions of the observer and the aircraft are shown in the given figure.
Height of the aircraft from ground, OR = 3400 m
Angle subtended between the positions, ∠POQ = 30°
Time = 10 s
In ΔPRO:
tan 15° =
PR = OR tan 15°
=
ΔPRO is similar to ΔRQO.
∴PR = RQ
PQ = PR + RQ
= 2PR = 2 × 3400 tan 15°
= 6800 × 0.268 = 1822.4 m
∴ Speed of the aircraft =
= 182.24 m/s m/s
Q7. In PPP Parity means
Answer : Option C
Explaination / Solution:
Purchasing power parity (PPP) is an economic theory that states that the exchange rate between two currencies is equal to the ratio of the currencies' respective purchasing power.
Q8.
Arrange the order of events taking place in anaphase II stage of meiosis:
a. Metaphase plate spilts
b. Each chromosome moves away from equatorial plane
c. Centromeres split and chromatids separate.
d. Chromatids move to opposite poles
Answer : Option B
Explaination / Solution:
During anaphase stage, metaphase plate splits and each chromosome moves away from equatorial plane splitting the centromere and separate chromatids which move to opposite poles.
Q9. Which of the following processes does not involve a catalyst?
