    Remainder = 33q + 29//

    0Thank You

    Adithya Dev A 4 years, 6 months ago

    P = 11 * q + 6 = 11q + 6// (where q is quotient) (According to Euclid's division algorithm ie, Divident = Quotient * Divisor + Remainder). Therefore, r = 4P + 5 - 11q = 4 (11q + 6) + 5 - 11q = 44q + 24 + 5 - 11q = 33q + 29// Therefore, remainder = 29.

    First prove that √3 is irrational. Then, since the sum of a rational and an irrational number is always irrational, 2 + √3 will also be IRRATIONAL in nature.

    p (x) = ax^2 - 6x - 6 = 0. Now, according to the relationship between zeroes and coefficients in a quadratic equations, (if α and β are the zeroes of p (x)), αβ = C/A. 4 = -6/a. Therefore, a = -6/4 = -1.5//

    Let father's age be x and the sum of sons' ages be y. Therefore, x = 3y OR, x - 3y = 0 (1). Now, 5 years later, father's age = (x + 5) years. Sum of sons' ages = (y + 5 + 5) = (y + 10) years. Therfore, x + 5 = 2 (y + 10). x + 5 = 2y + 20. x - 2y = 15 (2). Solving (1) and (2), x = 45 and y = 15. Therefore, father's age = 45 years//
