QUANTS

1. Given f(n+3)=f(n) and
f(-1)=6
f(0)= 5
f(1) = 4
then the value of f(8) is ?
Ans: 6
Explanation: The equation f(n+3)=f(n) means that f(n) value repeats once in three turns . For eg., if f(0)=5 then f(3) will also b 5 ,where n=0. Hence F(8) = 6

2. A circle is inscribed in a square of side 2m.
ColA: area of circle
ColB: pie
Ans: C
Explanation: The radius of the circle will b 1m so the area will b pie. Hence both are equal

3. x^2+2x-8=0
Col A:The sum of the roots
Col B: -2
Ans: C
Explanation: The root of the equation wld b -4 and 2 . Adding The roots will give -2. Hence they are Equal

4. An regular pentagon and an equilateral triangle were given. The perimeter of pentagon is twice that of triangle.
Col A: Side of pentagon
Col B: Side of triangle
Ans: A
Explanation : A pentagon has 5 sides n triangle has 3 sides . when sum of 5 sides s twice that of a triangles perimeter i.e sum of 3 sides of a a triangle ,its implied that side of pentagon s larger

5. A telephone company has no.'s between 3000-3799. A Company called X uses the numbers from 3300-3499. Out of these managers of Division1 level use numbers ending with 0 or 1. What percent of the telephone company numbers are used by Managers of Division1 level of Comany X?
Ans: 5%
Explanation: From 0 to 99 we have 20 digits ending with 0 and 1. Between 3300 – 3499 we have 40 digits . 40 is 5% in 800

6. A triangle ABC is given. A point D divides the side AB such that a trainge ADC is formed and AD/DB=1/3. If the area of the triangle ABC is r. Find the area of the triangle ADC in terms of r?Ans: r/4
Explanation: The ratio of sides AD:DB = 1: 3 (given). Assume the side AB is of length x ,So the side AD is (¼)x . When length was x the area was r , when the length is (1/4) x the area will b ?. slolving we get area= r/4.

7. If x is a positive number which leaves a remainder 2 when divided by 8 and when divided by 5 it leaves a remainder 3. Find the least possible number?
col A: x
col B: 18
Ans: C
Explanation: 18 is the least no that gives a reminder 2 when divided by 8 and when divided by 5 it leaves a remainder 3. Taking 10 will giv reminder 2 for 8 but it gets divided by 5. so the next choice is 18.

8. In a room there are more than 12 members which are divided into a 5 member group and a 8member group and a 12 member group. Find the least possible members in that room such that finally none were left?
Col A the members in the room
Col B: 120
Ans: C
Explanation: The LCM of 5,12,8 will b 120 .

9. A rectangular aquarium base has dimensions 10*8 and height 10. Aquarium is filled upto the height of 6, a solid bar is immersed into it... there by increasing the water level to 7.
Col a: the bar dimensions
Col b: 100 cubics
Ans:B
Explanation: The height of the bar is 1 (7-6) and the dimension of it will b
80(10*8). Hence Col B s greater.

10. Col A: 50 square + 51 Square + 52 square
Col B: 3(square of 52)
Ans: B
Explanation: The (Square of 52 ) is grerater than (Square of 51 ) and (Square of 50) , hence thrice its value will be greater than sum of squares of 50 , 51 and 52. Col B is greater.
