I) x2− (a + b)x – (192+ 53) = 0
II) y2 + (a * b)y – (212 - 50) = 0
III) z2 + (a3 + b3 + c - 4)z + (d2 - 137) = 0
Note:
- (a - b) = 1 and sum of the squares of ‘a’ and ‘b’ is 13 and a and b are positive numbers.
- Difference between the value of ‘c’ and ‘d’ is (a * b).
- Value of c and d are consecutive prime number (less than 50) and the value of d is more than 25 and the value of c is less than 30.
If A, B, and C can do the work in 4b, 4a, (c - 7) days respectively and efficiency of D is 50% more than C. A and B worked for ‘a’ days remaining work done by C and D in how many days?
