1. Aruna cut a cake into two halves and cuts one half into smaller pieces of equal size. Each of the small pieces is twenty grams in weight. If she has seven pieces of the cake in all with her, how heavy was the original cake ?

  • 240 gm
  • 220 gm
  • 225 gm
  • 250 gm

Answer: Option A

2. A certain number of horses and an equal number of men are going somewhere. Half of the owners are on their horses' back while the remaining ones are walking along leading their horses. If the number of legs walking on the ground is 70, how many horses are there ?

  • 8
  • 10
  • 12
  • 14

Answer: Option D

Explanation:

Let number of horses = number of men = x.

Then, number of legs = 4x + 2 x (x/2) = 5x.

So, 5X = 70 or x = 14.

3. Reena is twice as old as Sunita. Three years ago, she was three times as old as Sunita. How old is Reena now ?

  • 6 years
  • 12 years
  • 14 years
  • 16 years

Answer: Option B

Explanation:

Let Sunita's present age = x years
Then Reena present age = 2x years

Three years ago
(2x-3) = 3(x-3)
2x - 3 = 3x - 9
or x = 6

Reena age = 2x = 2*6 = 12 year.

4. First bunch of bananas has (1/4) again as many bananas as a second bunch. If the second bunch has 3 bananas less than the first bunch, then the number of bananas in the first bunch are

  • 9
  • 10
  • 12
  • 15

Answer: Option D

Explanation:

Let the number of bananas in the second bunch be x.
Then, the number of bananas in the first bunch
= x + 1/4 x
= 5/4 x
So,
5/4 x - x = 3
=> 5x - 4x = 12
x = 12

Number of bananas in first bunch
= 5/4 * 12 = 15

    According to Question ,
    CAT 100 : 4 : : 100 : X
    MICE 100 : 4

    CAT = 100:4(Less cat more days) Indirect
    Mice = 100:4 (Less mice less days) Direct

    In Direct proportion, ratio will same.
    but in Indirect proportion, ratio will exchange.

    So, CAT is Indirect then , ratio of CAT will be = 4:100

    CAT 4 : 100 : : 100 : X
    MICE 100 : 4

    Then solution is,
    X*4*100 = (100*100*4)

    then X = (100*100*4)/(100*4)

    Answer is 100 Days.
