If 460 is divided by a natural number quotient is 6. more than five times the divisor and remainder is 1 find quotient and diviser
Answers
Step-by-step explanation:
let the divisor be 'x'
the the quotient is (6+5x)
we know that
divident = divisor ×quotient +remainder
460=x(6+5x)+1
460=6x+5x²+1
460=5x²+6x+1
5x²+6x+1-460=0
5x²+6x-459=0
5x²-45x+51x-459=0
5x(x-9)+51(x-9)=0
(5x+51)(x-9)0
5x+51=0 or x-9=0
5x=-51 or x=9
x=-51/5 or x=9
but -51/5 is not a natural number
thus x= 9
remainder=9
quotient = 5x+6=5(9)+6=45+6=51
the quotient is 51 and the remainder is 9

Answer:
If 460 is divided by a natural number quotient is 6 more than five times the divisor and remainder is 1, the quotient and divisor are 51 and 9 respectively.
Step-by-step explanation:
Let the natural number be x.
Since we have a remainder of 1, the quotient is given by:
(460 - 1)/x = quotient
Now, the quotient is 6 more than 5 times the divisor. So, we have:
quotient = 5x + 6
Substituting this in the first equation we have:
(460 - 1)/x = 5x + 6
459/x = 5x + 6
459 = 5x² + 6x
We get a quadratic equation.
Solving it we have:
5x² + 6x - 459 = 0
Applying the quadratic formula we have:
x = [-6±√(6² + 4 × 459 × 5)]/(2 × 5)
x = [-6±96]/10
x = 9 or -10.20
We take 9 since it's a natural number.
So, the divisor in this case is 9.
The quotient = 5 × 9 + 6 = 51
