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,
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). |

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 |
