Question

if the no. of apples and mangoes are the zeroes of the polynomial 3x^2=8x- 2k+1 and the no. of apples is 7 times the no. of mangoes,then find the no. of zeroes and values of k . what are benefits of fruits in our daily life?

Answer 1

let no. of apples be P
and no.of mangoes be Q

given that 7Q=P

also P+Q=8/3......sum of roots

we get Q=1/3 ....

=>P=7/3


and PQ=(2k-1)/3......product of roots
7/9=(2k-1)/3

k=5/3

no.of zeroes is P+Q=8/3
and benefits of fruits!

fruits are rich in fibre and vitamins
helps in better digestion and increasing metabolism!!
As an apple a day keeps the doctor away!
