How many pears did the Type B trees produce?

Type A trees produced 20 percent more pears than Type B trees did
Type A trees produced 144 pears.

Let us consider, Type B produced 100% pears.

So, Type A will produce 120%of B, that is 144

144 = 120/100 [tex]*[/tex] B

simplifying the above equation, we get

144 [tex]*[/tex] 100 = 120B

B = 14400/120

B = 120

The value of B = 120.

Hence, the Type B trees produces 120 pears

Therefore, the correct answer is option B) 120.
