# Math Part:

33. The values of p for equation 2x²-4x+p = 0 to have real root is: —- to have one or more real roots, b²-4ac ≥ 0 or, (-4)² – 4×2×p ≥ 0 or, -8p ≥ -16 or, p ≤ 2. ————————————————– [C] .

34. How many integers from 1 to 100 are divisible by 3 but not by 8? —- divisible by 3 = 100/3 = 33 integers divisible by 8&3, or 24 = 100/24 = 4 divisible by 3 but not by 8 = 33-4 = 29. ————————————————– [B]

35. If x:y = 5:3, then (8x+5y) : (8x-5y) = ? — x:y = 5:3 x = 5y/3 8x = 40y/3 (8x+5y) : (8x-5y) = (40y/3 + 5y) : (40y/3 – 5y) = 55y : 25y = 11 : 5. ————————————————– [D]

37. If a+1/a = 2, what is a³ + 1/a³? —- (a+1/a) = 2 => a³ + 1/a³ + 3×a×1/a×(a+1/a) = 2³ => a³ + 1/a³ + 3×2 = 8 => a³ + 1/a³ = 2. —– [C]

. 38. If 10% of x is equal to 25% of y, and y = 16, what is the value of x? —- x × 10/100 = y × 25/100 2x = 5y = 5×16 = 80 x = 40. ———– [D]

39. If sinA + sin²A = 1, then the value of the expression (cos²A + cos⁴A) is — —- sinA + sin²A = 1 => sinA + sin²A = sin²A + cos²A => cos²A = sinA cos²A + cos⁴A = sinA + sin²A = 1.– [A]

.

40. A pole casts a √3m long shadow on the ground at an elevation 60°, the height of the pole is — . Θ = 60°, b = √3, h = ? we know, tanΘ = h/b tan 60° = h/√3 √3 = h/√3 h = 3. ——– [A]
