A.57%
B.60%
C.65%
D.90%
Ex:Total number of votes polled = (1136 + 7636 + 11628) = 20400.
∴ Required percentage =(11628/20400)x 100% = 57%

2.Raman's salary was decreased by 50% and subsequently increased by 50%. How much percent does he loss?
A.Rs. 25
B.Rs. 50
C.Rs. 75
D.Rs. 85
EX:Let the original salary = Rs. 100.
New final salary = 150% of (50% of Rs. 100)

3.Railways fares of 1st, 2nd and 3rd classes between two stations were in the ratio of 8:6:3. The fares of 1st and 2nd class were
subsequently reduced by 1/6 and 1/12 respectively. If during a year, the ratio between passenger of 1st, 2nd and 3rd classes was
9:12:26 and total amount collected by the sale of tickets was Rs 1088, then find the collection from the passengers of 1st class.
A.Rs 260
B.Rs 280
C.Rs 300
D.Rs 320
Answer Ex:New ratio of fares (1st, 2nd and 3rd)= 8 x1/5:6 x11/12:3 x 1 = 40 : 33 : 18
Ratio of passengers = 9 : 12 : 26
Ratio of amount collected = 40 x 9 : 12 x 33 : 26 x 18= 90 : 99 : 117
Amount collected from 1st class fares = (90/306) x 1088 = Rs 320

4.If √2n = 64, then the value of n is
A.2
B.4
C.6
D.12
Answer Ex:Given,√2n = 64
⇒ (2n)1/2 = 26
⇒ (2)n/2 = 26
⇒n/2= 6
= 12

5.If ax =b, by= c and cz= a, then the value of xyz is
A.0
B.1
C.1/abc
D.abc
Ex:a1 = cz.
= (by)z.
= (byz).
= (ax)yz.
Therefore, xyz= 1

6.The sum of ages of 5 children born at the intervals of 3 years each is 50 years. What is the age of the youngest child?
A.4 years
B.8 years
C.10 years
D.None of these
Let the ages of children be x, (x + 3), (x + 6), (x + 9) and (x + 12) years.
Then, x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50
⇒ 5x = 20
⇒ x = 4
∴ Age of the youngest child = x = 4 years.

7.Q is as much younger than R as he is older than T. If the sum of the ages of R and T is 50 years, what is definitely the difference
between R and Q's age?
A.1 year
B.2 years
C.25 years
E.None of these
Answer EX:R - Q = R- T ⇒ Q = T.
Also, R + T = 50 ⇒ R + Q = 50.
So, (R - Q) cannot be determined.

8.The least number which should be added to 2497 so that the sum is exactly divisible by 5, 6, 4 and 3 is:
A.3
B.13
C.23
D.33
Ex:L.C.M. of 5, 6, 4 and 3 = 60.
On dividing 2497 by 60, the remainder is 37.
∴ Number to be added = (60 - 37) =23

9.A rectangular court 3.78 metres long and 5.25 metres wide is to be paved exactly with square tiles, all of the same size. What is
the largest size of the tile which could be used for the purpose?
