Median of the numbers $18, 21, 25, 27, 2x-1, 3x-6, 45, 48, 51, 57$ given in ascending order is 34. What is the value of $x$ ?
Answer & explanation
Correct answer: option 3
Median of the numbers $18, 21, 25, 27, 2x-1, 3x-6, 45, 48, 51, 57$ given in ascending order is 34,
Now the value of the median is decided by two terms = 2x-1, 3x-6
Median = sum of terms/no. of terms
= (2x-1 + 3x-6)/2 = 34
= (5x-7)/2 = 34
= 5x-7 = 68
= x = 15
