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!
