Direction: Whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer:

0

Q. What is the value of three digits number, the unit digit of which is 3 and divisible by 7?
Statement I: The three digits number is divisible by 9.
Statement II: The three-digit number is divisible by 21.

  • (A). The data in statements I alone is sufficient to answer the question,
    while the data in statement II alone is not sufficient to answer the question.
  • (B). The data in statements II alone is sufficient to answer the question,
    while the data in statement I alone is not sufficient to answer the question.
  • (C). The data in both the statements I and II is not sufficient to answer the question.
  • (D). The data in both the statements I and II together is necessary to answer the question.
Option (A) is Correct

From the question, the unit digit of the three-digit number is 3, and it is divisible by 7.
From the statement I, the number is divisible by 9
LCM of 9 and 7 = 63
The only number which is multiple of 63 and the unit digit of which is 3, is 63 × 11 = 693
Therefore, we can conclude our answer by this statement
From the statement II, the number is divisible by 21 therefore, LCM of 21 and 7 = 21
There are many numbers like, 273, 483 —- which is divisible by 21 and 7, and the unit digit of which is 3
Therefore, we could not get a unique answer by this statement.
Therefore, the data in statements I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.

Q. Find the value of (?) in given series:
2, 4, 12, ? , 3612

  • (A). 12
  • (B). 84
  • (C). 256
  • (D). 578
Option (B) is Correct

The pattern is, $$x^2/2+x$$

Q. The salaries of A,B and C are in the ratio 5:3:2. If the increments of 20% ,10% and 20% are allowed in their salaries, then what will be the new ratio of their salaries ?

  • (A). 22:11:9
  • (B). 22:10:8
  • (C). 20:11:8
  • (D). 20:10:9
Option (C) is Correct

Q. Two numbers are respectively 25% and 50% more than a third number. The ratio of the two numbers is:

  • (A). 3 : 5
  • (B). 5 : 6
  • (C). 5 : 4
  • (D). 4 : 5
Option (B) is Correct

Let the third number be $$x$$
then, first number = $$125%ofx=125x/100=5x/4$$
second number = $$150%ofx=150x/100=3x/2$$
$$therefore$$ Ratio of first two numbers=$$5x/4 : 3x/2 = 10x : 12x = 5 : 6$$

Direction: On the basis of these equations you have to decide the relation between ‘x’ and ‘y’ and give answer.

Q. I. $$6x^2-19x+15=0$$
II. $$10y^2-29y+21=0$$

  • (A). $$x>y$$
  • (B). $$x<y$$
  • (C). $$x>=y$$
  • (D). $$x<=y$$
  • (E). $$x=y$$ or CND
Option (C) is Correct

$$x=5/3, 3/2$$
$$y=7/5, 3/2$$
$$so, x>=y$$
