Answer:
the number of activity card holders is 128 and non-card holders is 75 respectively
Explanation:
Let us assume the activity card holders be x
And, the non-card holders be y
Now as per the given situation
x + y = 203
x = 203 - y
1.25x + 2y = 310
Now put the value of x in the above equation
1.25(203 - y) + 2y = 310
253.75 - 1.25y + 2y = 310
0.75y = 56.25
y = 75
And,
x = 203 - 75
= 128
Hence, the number of activity card holders is 128 and non-card holders is 75 respectively
