Answer:

84

Step-by-step explanation:

If there are 5 scores and the Mean of the scores =88

Total Scores=88X5=440

If Mode =92 and Median=87.

Mode us the number with the highest frequency.

Median is the middle term when arranged in ascending order.

Therefore, the numbers are:

x,y,87,92,92

92+92+87=271

The other two scores (x,y) add up to: 440-266=169

The average of the other two numbers is:

169/2 = 84.5

The minimum possible value of x is 84.
