Let's say - the lots are x, y and z and X has the largest number of parts

given => x+ y + z = 70 - question - Find X?

statement 1 : x = y + z

substituting in the given equation : 2(y+z) = 70 so y + z = 35 = x : Sufficient

Statement 2: either y or z = 10 : nothing on x hence insufficient

Ans : A

(1) The number of items in the largest lot is equal to the sum of the number of items of the other two lots.

lets say 3 lots are L1, L2, and L3 and L1 the is largest lot.

As per given condition -
L1+L2+L3 = 70
L1 = L2+L3
so L1 + L1 = 70
L1 = 35

St1 is sufficient to get L1 size.

Your stated example in St1. don't satisfy given condition.

50 is not equal to 10+10.
