in a flower bouquet 13/30 of the flowers were roses 2/5 of the flowers were orchids and the remaining were gladioli if the number of gladioli were 7, how many flowers were there in bouquet

Answer»

Roses = 13/30 So remaining = 17/30

Orchid = 2/5 out of 17/30 So remaining = 17/30 - 2/5 = (17-12)/30 = 5/30

Gladioli = 7 that is 5/30

Let TOTAL flower = x

So 5/30 of x = 7

5/30 * x = 7

x = 7 * 30/5

x = 42

Total flowers = 42

A quadratic equation with rational coefficients one of whose roots is tan(Pie/12) is

Answer»

Tan (pi/12) = 2- rt3
Since irrational roots always OCCUR in conjugate pairs
Therefore other ROOT = 2+ rt3
a= 2-rt3 b= 2+ rt3
Therefore the quadratic equation
x^2 - (a+b) x + ab
x^2 -( 2- rt3 + 2 + rt3) x + (2-rt3)(2+rt3)
x^2- 4x + 1= 0 is the required quadratic equation
