A. 12
B. 6
C. 9
D. none

these are question tht are seem to be like it consumes
time. so dont see jus the question and run to the next .
ans. a) 12
if 9 balls are added then the ratio to the combination
becomes 2:4:3.
9 balls make the ratio 3 for grey balls in tht mixture.
so the factor is 9/3 = 3 (in tht mixture)
so the same factor has to be maintained through out the
ratio. so black balls is 4 * 3 = 12 and white balls is 2 *
3 = 6.

Ques:- One student takes 20 mins to reach school if he goes at a speed of 15kmph .At what speed should he go to reach in 15 mins ?

1) time =20mins,speed=15kmph=15*(5/18)=25/6 m/sec
distance=20*(25/6)=250/3 m
then 2) given as time =15min
speed=250/3*15=(50/9)*(18/5)kmph=20kmph

Ques:- Cost of an item is x. It’s value increases by p% and decreases by p% Now the new value is 1 rupee, what is the actual value ?

Ques:- The ratio between the present ages of A and B is 5:3 respectively. The ratio between A’s age 4 years ago and B’s age 4 years hence is 1:1. What is the ratio between A’s age 4 years hence and B’s age 4 years ago?

x = 5/3y
x – 4 = y + 4
x – 8 = y
x = 5/3 * (x-8)
5/3x – 40/3 = x
2/3x = 40/3
2x = 40
x = 20
y = 20 – 8
y = 12
x + 4 = 24
y – 4 = 8
Ratio is 24:8 , so 3:1

Ques:- Find the odd man out:

B. 1440
C. 1080
D. 960

C)1440
2*2=4
4*3=12
12*4=48
48*5=240
240*6=1440

Ques:- In a round table conference six persons are participating, They are Andy, Bob, Charles, Douglas, Elena and Fred. Bob is sitting between Charles and Elena and is opposite to Andy. Douglas is sitting to the left of Elena. Who is sitting opposite to Douglas?

X×x-x=272
X^2-x-272=0
(X-16) or (x-17)
X=16 or x=17

17^2-17=272

Let three consecutive even numbers be 2n,2n+2,2n+4
product=2n(2n+2)(2n+4)
If n=1,
product =2(4)(6)=48.
So, all the numbers will be divisible by 48 if change n.
