Hey guys, Please help me with the solutions for these questions..

1. What is the difference between the total number of factors and prime factors of

(60^3-32^3-28^3) ??

Answer: 116

2. (X^2-1) is a factor of

f(X)= X^5+aX^4+bX^3+cX^2+X+d

Then, F(X) intersects Yaxis at (0,-3). Find the value of(a+c)

Ans. 3

3. According to a survey, atleast 70% like apples, atleast 75% like bananas and atleast 80% like cherries. What is the minimum % who like all the three??

Ans. 25%
