- A bag contains (x + 1), green balls and (x + 4) yellow balls. If one ball is drawn at random from the bag, the probability of getting a green ball is 3/7. Find the total number of balls in the bag ?
3423284221Option E

Probability = 3/7

x + 1/x + 1 + x + 4 = 3/7

x + 1/2x + 5 = 3/7

x = 8

total balls in the bag = 9 + 12 = 21 balls - A alone can do a work in 20 days and efficiency of A is 7 1/7% more than B. If efficiency of C is 20% less than A, then find in how many days B and C together can complete the same work ?
100/9 days15 days18 days200/3 days30 daysOption A

Fraction value 7 1/7% = 1/14

efficiency of B = 14

efficiency of A = 15

total work = 15 * 20 = 300

efficiency of C = 15 * 4/5 = 12

time = 300/15 + 12 = 100/9 days - The ratio of milk and water in a mixture is 11 : 4. When 30 liters of mixture is taken out and 18 liters of milk is added in the remaining mixture, the ratio of milk to water is 5 : 1, find the initial quantity of milk.
44 liters65 liters40 liters50 liters62 litersOption A

Let quantity of milk = 11x

and water = 4x

(11x – 30 * 11/15 + 18)/4x – 30 * 4/15 = 5/1

11x – 4/4x – 8 = 5/1

11x – 4 = 20x – 40

x = 4

initial quantity of milk = 11 * 4 = 44 liters - An amount is divided among A, B and C, amount of B is average of amount A and C and when amount of B is reduced by 20% of that of A, it becomes equal to that of C. Find amount of C is what percent of total amount ?
20%30%40%15%25%Option E

Let amount of A and C is rs.x and rs.y respectively.

amount of B = x + y/2

x + y/2 – x/5 = y

3x = 5y

x/y = 5/3

amount of A = rs.5a

amount of B = rs.4a

amount of C = rs.3a

% = 3a/12a * 100 = 25% - Train A running at speed of 108 km/hr crosses a platform having twice the length of train in 24 sec. Train B whose length is 420m crosses same platform in 36 sec, then find the speed of train B ?
108 km/hr45 k/hr76 km/hr90 km/hr72 km/hrOption D

Let length of train A = x

length of platform = 2x

x + 2x/24 = 108 * 5/18

x = 240m

let speed of train B is y km/hr

420 + 2 * 240/36 = y * 5/18

y = 90 km/hr - Directions : In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and give answer

I. x^2 – 17x – 84 = 0

II. y^2 + 4y – 117 = 0X > YX < YX â‰¥ YX â‰¤ YX = Y or no relation.Option E

I. x^2 – 21x + 4x – 84 = 0

x = 21, -4

II. y^2 + 13y – 9y – 117 = 0

y = -13, 9 - I. x^2 + 23x + 132 = 0

II. y^2 + 21y + 110 = 0X > YX < YX â‰¥ YX â‰¤ YX = Y or no relation.Option D

I. x^2 + 12x + 11x + 132 = 0

x = -12, -11

II. y^2 + 11y + 10y + 110 = 0

y = -11, -10 - I. x^2 = 196

II. y = âˆš196X > YX < YX â‰¤ YX â‰¥ YX = Y or no relation.Option C

I. x^2 = 196

x = 14, -14

II. y = âˆš196

y = 14, 14 - I. 3x^2 + 13x + 12 = 0

II. y^2 + 9y + 20 = 0X > YX < YX â‰¥ YX â‰¤ YX = Y or no relation.Option A

I. 3x^2 + 9x 4x + 12 = 0

3x = -9, -4

x = -3, -1.33

II. y^2 + 5y + 4y + 20 = 0

y = -5, -4 - I. x^3 = 216

II. 2y^2 – 25y + 78 = 0X > YX < YX â‰¥ YX â‰¤ YX = Y or no relation.Option D

I. x^3 = 216

x = 6

II. 2y^2 – 13y – 12y + 78 = 0

2y = 13, 12

y = 6.5, 6

Definitely believe that which you said. Your favorite justification seemed to be on the internet the simplest thing to be aware of.

I say to you, I certainly get annoyed while people consider worries that they plainly don’t know about.

You managed to hit the nail upon the top and defined out the whole thing without having side effect , people can take a signal.
