The sum of the digits of a 2-digit no is 10. The no. Obtained by interchanging the digits exceeds the original no. By 36. Find the original no |
|
Answer» Let the number be xy , where X is the digit at 10's place and y is the digit at unit's place. Given, x+y=10 --------------------- ( 1 ) Original value = 10x+y After interchanging the digits the NEW number is yx and it's value is 10y+x . Given , 10y+x = 10x+y + 36 ----------------- ( 2 ) => 9y = 9x + 36 => y = x + 4 -------------------------- ( 3 ) From (1) and (3) , x+x+4=10 => x=3 and y= 7 Therefore, the original number is 37. |

Circles class 10.... |
|
Answer» Assume angle OBD as x Make 2 constructions - OD and any point Q on the circle to join AQ and DQ Now, angle ODB is equal to OBD (isosceles triangle DOB) equal to x Angle AOD = ODB+OBD = 2x Angle AQD = 2x/2 = x (angle subtended on circle) AQDC is cyclic quadrilateral So angle ACD is 180-x (Result 1) Line segments OD, CD and OC are equal to radius, so ODC is equilateral triangle. Angle ODC is 60 deg. Angle CDP is THUS 180-60-x=120-x Now, angle CPD+angle CDP=angle ACD. Combining with Result 1, Angle CPD=180-x-120+x=60 degree Took less TIME to solve, but forever to write! |

Show that out of every four consecutive positive integer one will be divisible by four. |
|
Answer» Proof by contradiction: Let the 4 nos be a,a+1,a+2,a+3 - NONE of which are divisible by 4 Nos not divisible by 4 are either 4k+1,4k+2 or 4k+3, where k is a whole number Case 1: a is 4k+1 Now, a+3 BECOMES 4k+4 which is divisible by 4 - so this case is not possible Case 2: a is 4k+2 Now, a+2 becomes 4k+4 which is divisible by 4 - so this case is not possible Case 3: a is 4k+3 Now, a+1 becomes 4k+4 which is divisible by 4 - so this case is also not possible We have exhausted all possible cases, and in all cases non-divisibility by 4 is impossible. Hence proved by contradiction |
