4
5
6
7

hint Hint:

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers. Find the mean of the given data and equate it with given value of the mean to find x .

The correct answer is: 6

Data : 3, 4, x, 7, 10 Mean = 6
Mean = $fraction numerator s u m blank o f blank n u m b e r s over denominator n u m b e r blank o f blank n u m b e r s end fraction$
6 = $fraction numerator 3 blank plus blank 4 blank plus blank x blank plus blank 7 blank plus blank 10 over denominator 5 end fraction$
