The average of 5 numbers is 42. If one number 32 is removed, the new average is:
Sum = 210. New sum = 178. Average = 178/4 = 44.5.
Reasoning
Find next number: 3, 6, 12, 24, 48, ?
Pattern: Each number = previous × 2 3×2=6, 6×2=12, 12×2=24, 24×2=48 Next: 48×2 = 96
Quantitative
If the sum of the first n natural numbers is 210, what is the value of n?
Sum = n(n + 1)/2 = 210 n(n + 1) = 420 n² + n - 420 = 0 (n + 21)(n - 20) = 0 n = 20 (positive value)
Verbal
