Answer: 40
Explanation A.M=Sum/total A.M. of 75 numbers = 35 Sum of 75 numbers = 75 * 35 = 2625 Total increase = 75 * 5 = 375 Increased sum = 2625 + 375 = 3000 Increased average = 3000/75 = 40

Explanation
Answer: 15
Explanation Let’s analyze the pattern: 90 → 85 (−5) 85 → 75 (−10) 75 → 55 (−20) The subtraction pattern is: −5, −10, −20 … each time doubling. Next should be: −40 So, 55 − 40 = 15

Answer: XVII
Explanation The series is formed by incrementing the Roman numerals by 3: V (5) + 3 = VIII (8) VIII (8) + 3 = XI (11) XI (11) + 3 = XIV (14) XIV (14) + 3 = XVII (17) So, the next number in the series is XVII.
Answer: 30°
Explanation The ratio of the length of the rod to its shadow is 1:√3. This ratio is equal to the tangent of the angle of elevation of the sun (tan(θ) = opposite/adjacent). So, we can set up the equation: tan(θ) = 1/√3 To find the angle θ, we take the inverse tangent (arctangent) of both sides: θ = arctan(1/√3) Using a calculator or trigonometric tables, we find that θ = 30°
