14. The ten's digit of a two digit number is three timesthe unit digit. The sum of the number and the unitdigit is 32. Find the number.c.+​

Answer»

Let the TWO numbers be x and y. If x is the number in the 10th DIGIT and y is the UNIT digit, then

x = 3y

and 10x+y+y = 32

10x + 2y = 32

and x = 3y. Substituting the value of x in 10x+2y = 32, we get

10 * 3y +2y = 32

or 32y = 32 or y = 1

and x = 3.

Thus, the number is 31.

The interior angles of a quadrilateral are (2x+15), (2x - 5),(3x + 75) and (3x - 25) the smallest interior angle of the quadrilateral.

Answer»

Answer:

55°

Step-by-step explanation:

LET there is a quadrilateral ABCD.

Given that,

  • A = (2x+15)
  • B = (2x-5)
  • C = (3x+75)
  • D = (3x-25)

Now, we know that,

Sum of all INTERIOR angles of a quadrilatral is equal to 360°.

Therefore, we will get,

=> 2x+15+2x-5+3x+75+3x-25 = 360

=> (2x+2x+3x+3x) + (15-5+75-25) = 360

=> 10x + 60 = 360

=> 10x = 360-60

=> 10x = 300

=> x = 300/10

=> x = 30

Therefore, we will get,

=> A = 2(30) + 15 = 60+15

=> A = 75°

=> B = 2(30) - 5 = 60-5

=> B = 55°

=> C =3(30) + 75 = 90+75

=> C = 165°

=> D = 3(30) - 25 = 90-25

=> D = 65°

Hence, smallest of the interior angles is B, i.e., 55°, i.e., (2x-5).

Write a pair of integers whose sum is 15 and difference is - 9

Answer»

ANSWER: 3 and 12

Step-by-step explanation:

Let the integers be X and y.

x+y=15

x-y=-9

Add both equations-

x+y+x-y=15+(-9)

2x=6

x=3

We KNOW x+y=15

3+y=15

y=12

Therefore the integers are 3 and 12.

Eight railway stations A, B, C, D, E, F, G and H are connected either by two way passage or one way passages.One way passages are from C to A, E to G,B to F, D to H, G to C, E to C and H to G. Two way passagesare between A and E, G and B, F and D, and E and D.ques -While travelling from C to H, which one of the followingstations must be passed through.(a) G(b) E(c) B(d) F In how many different ways can a train travel from F to A without passing through any station more than once? (a) 1(b) 2(c)3(d)4​

Answer»

Given

Total number of STATIONS = 8

Total number of passages = 2

ONE way PASSAGE =  C to A, E to G,B to F, D to H, G to C, E to C and H to G

Two way passage = between A and E, G and B, F and D, and E and D.

To find:

While travelling from C to H, which stations must be passed through.

In how many different ways can a train travel from F to A without passing through any station more than once.

Solution:

One way passage CONNECTIONS -

C-A, E-G, B-F, E-C, H-G, D-H, G-C

Two way passages -  

A=E, G=B, E=D, F=D

1. If we want to travel from c to h there is only one possibility to go to A.

From A only one to go to E. THUS, it needs to pass through E.

2. Following the path - F-D-E-C-A, F-D-H-G-C-A, F-D-E-G-C-A  or F-D-E-A

Thus total ways = 4
