Answer:

Mark picked 35 cherries.

Step-by-step explanation:

Let sherry's cherry and mark's cherry be x and y respectively,

x + y = 75

x = 75 - y.....eqn ii

y - 15 = x/2...eqn ii

substituting eqn ii in eqn i,

y - 15 = x/2

or, y - 15 = (75 - y)/2

or, 2y - 30 = 75 - y

or, 2y + y = 75 + 30

or, 3y = 105

so, y = 35
