Tanushka Panwar 4 years, 6 months ago

Triangle is the polygon with minimum number of sides and an equilateral triangle is a regular polygon because all sides are equal in this. We know that each angle of an equilateral triangle measures 60 degree. Hence, 60 degree is the minimum possible value for internal angle of a regular polygon.

Let the digits at unit place be y. Let the digits at ten's place be x.
Number = 10x + y
Sum of digits of the two digits number is four times that in the unit's place. => x + y = 4y => x = 4y - y => x = 3y ......(i).
If the digits are reversed the new number will be 54 less that the original number.
Number obtained by reversing the digits = 10y + x
Number obtained by reversing the digits = 10x + y - 54 => 10y + x = 10x + y - 54 => 54 = 10x + y - 10y - x => 54 = 9x - 9y => 54 = 9(x - y) => 54/9 = x - y => 6 = x - y .........(ii).
Putting the value of x from Eq (i). in Eq (ii). => 6 = x - y => 6 = 3y - y => 6 = 2y => y = 6/2 => y = 3
Putting the value of y in Eq (ii). => 6 = x - y => 6 = x - 3 => -x = -6 - 3 => -x = -9 => x = 9
So, Number = 10x + y => 10(9) + 3 => 90 + 3 => 93
Hence, the original number is 93.

Preeti Dabral 4 years, 6 months ago

To find the rational numbers between 1/2 and 3/4 let us first equate the denominators (1/2) (2/2) = 2/4 (3/4)(1/1)=3/4 Now we have 2/4 and 3/4 Now will multiply both the fractions Numerator and denominator by 10. We get 20/40 and 30/40 Hence will find rational numbers now between 20/40 and 30/40 The rational numbers are 21/40. 22/40, 23/40, 24/40,25/40,26/40 and so on.
