Sushil was thrice as old as Snehal 6 years back. Sushil will be time as old as Snehal 6 years hence. How old is Snehal today.

let Snehal's age 6 years back =x

content, sushil's age 6 years back = 3x

(5 / 3)( x + 6 + 6 = (3 x + 6 + 6)

so 5 (x + 12 )= 3(3 X + 12)

so x = 6, Sanaya age = x+ 6

years = 12 years

The Cooking Club made some pies to sell at a basketball game to raise money for the new math books. The cafeteria contributed four pies to the sale. Each pies did the club make?

The total number of pies was 60/5= 12.

The cafeteria contributed : 4

So, the club must have made 12-4=8

In following questions, a sequence of groups of alphabets and numbers is provided with one term missing , Choose the missing term from options. 2Z5, 7Y7, 14X9, 23W11, 34V13, ?

The first numbers in the terms follow the sequence + 5, + 7, + 9, + 11, + 13. The middle letters form the series Z, Y, X, W, V, U.

The last numbers from the series 5, 7, ,9 , 11, 13, 15.

.
In following number series, two terms have been put within brackets. Choose the appropriate option

Choose the appropriate option 4, 6, 10, (12), 16, (14), 22

Choose the appropriate option 4, 6, 10, (12), 16, (14), 22

The correct sequence is + 2, + 4, + 2, + 4,...

Clearly, the term 12 is correct.

But, 14 is wrong and must be replaced by (16 + 2) i.e. 18..

Choose the term which will continue the following series : P 3 C, R 5 F, T 8 I, V 12 L, ?

Clearly, the first letters of the terms are alternate.

The sequence followed by the numbers is + 2, + 3, + 4, ... .

The last letter of each term is three steps ahead of the last letter of the preceding term.

Thus, the next term would be X 17 O.

Hence, the answer is (c).

An equilateral triangle is surrounded by three squares, as shown. What is the value of x?

We have labeled the diagram to help explain this answer. PR = RS because they are sides of a square, and RS = RT because they are sides of an equilateral triangle. RQ = RT because they are also sides of a square. Therefore RQ = PR. And because RQ and PR are sides of an isosceles triangle, angle RPQ = angle RQP. Right now remember that angles of a triangle totaled equals 180Â°. And angles of a square are all 90Â° and angles of an equilateral triangle are all 60Â°. Following? Good. So all the angles at point R must equal 360Â°. Soâ€¦ Angle PRQ = 360 â€“ (90 + 90 + 60) = 120. Therefore x = (360 â€“ 120) / 2 = 30.

There are a total of 42 computers . Each computer runs one of three operating systems: OSX ,Windows ,Linux .The ratio of the computers running OSX ,Windows, Linux is 2:5:7. Find the number of computers that are running each of the operating systems.

Let's x is the ratio between them

Then,

2x+ 5 x + 7 x = 42

14 x = 42

x = 42 / 14

X = 3

2 x = 2 ( 3) = 6 OSX

5 x = 5 ( 3) = 15 Windows

7 x = 7 x(3) = 21 Linux

In following number series, either one term is missing or is incorrect.

Choose correct answer from options 1, 5, 14, 30, 55, 93

Choose correct answer from options 1, 5, 14, 30, 55, 93

The correct sequence is + 4, + 9, + 16, + 25, + 36 i.e. + 2

So, 93 is wrong and should be replaced by (55 + 36) i.e. 91..

family consists of six members P, Q, R, X, Y and Z. Q is the son of R but R is
not mother of Q. P and R are a married couple. Y is the brother of R. X is the
daughter of P. Z is the brother of P. How is Q related to X ?

Option (C)

Q is the son of R but R is not the mother. So, R is the father of Q. P is married to R. So, P is the wife of R and the mother of Q. X is the daughter of P and hence of R and so she is the sister of Q. Y is the brother of R and Z is the brother of P. X is the sister of Q who is a male. So, Q is brother of X.
