Solutions

Volume of cube = 8x8x8 = 512 cm³.

Original volume of water = 25 x 20 x 5= 2500 cm³.

New volume = 2500 + 512 = 3012 cm³.

Actual volume to be reached is 25 x 20 x 8 = 4000 cm³.

Amount to be added = 4000 - 3012 = 988 cm³

D
3 ml

Solutions

Let the quantity of whisky and water be m and 5m respectively

m + 5m = 30

So, m = 5

Let y ml of water be added

=> 5/(25+y) = 2/11

=> 55 = 2y + 50

=> y = 2.5 ml

Solutions

The number of black balls =1200 X 35/100=420

Small black balls = 420 X 1/15=28

Big black balls= 420 X 65/100=273

Black balls( neither big nor small )= 420-(273+28)=119

White balls =1200 X 1/5=240

Small white balls = 240 X 1/6=40

Big white balls = 240 X 55/100=132

White balls that neither big nor small = 240-(40+132)=68

Difference = (273 - 40) = 233

C
if the question can be answered by using either of the statement alone.

Correct

Wrong

Skipped
D
if the question can be answered by using both of the statements together but not by either of the statement alone.

Solutions

Using statement (1) alone-

Let the total number of animals in zoo = x

All but 60 means all except 60.

Number of tigers in the Zoo = x-60

Number of lions in the forest = x-80

We don't know how many type of animals are there in the zoo hence we can't determine total number of animals in the zoo.

Using statement (2) alone-

Number of elephants in the Zoo = 10 and there are three types of animals in the zoo.

Using both the statements together

total number of animals in the zoo = x-60+x-80+10

x=x-60+x-80+10

x=130

so total animals in the zoo = 130

D

Solutions

Total employees in department P of company A = 50

Total male employees in department P of company B = 40

Total male employees in department P of company A = 40 * (3/4) = 30

Total female employees in department P of company A = 50 - 30 = 20

Total female employees in department P of company B = 40 - 15 = 25

Total employees in department P of company B = 40 + 25 = 65

Similarly, we can calculate other values .....

Total number of male employees in company A = 30 + 15 + 40 + 25 + 50 = 160

Total number of male employees in company B = 40 + 25 + 30 + 20 + 60 = 175

Difference = 175 - 160 = 15 less

Solutions

Let the price of one pen, one pencil and one table be Rs a, Rs b and Rs c respectively.

Using statement (1) alone-

We have; 6a + 5b + 4c = 2500 .. (1)

Using statement (2) alone-

We have; 4a + 3b + 2c = 1300 .. (2)

Using both the statements together-

2 X Equation (2) - Equation (1) => 2a + b = 100
