Let C be the number of cups of coffee sold on Sunday.
Let T be the number of cups of tea sold on Sunday.

C + 35 = T + 200

We know that the ratio of C to T is 4 : 1.

Therefore, C = 4T

So we can substitute:

4T + 35 = T + 200

Rearranging:

3T = 165

Simplify:

T = 55

Hence, the number of cups of tea sold on Sunday is 55.
