Question

Katerina is a botanist studying the production of pears by two types of pear trees. she noticed that Type A trees produced 20 percent more pears than Type B trees did. Based on Katarina's observation, if the Type A trees produced 144 pears, how many pears did the Type B trees produce?

Answer 1

Answer:

120 pears

Step-by-step explanation:

Let the  number of pears produced by Type B be x

Number of pears  produced by type A=144

  According to question

Type A produce 20% more pears than B

x+ x ×20%= 144

x+x×$\frac{20}{100}$= 144

$\frac{100x+20x}{100}$= 144

$\frac{120x}{100}$=144

x= 144×$\frac{100}{120}$

x=120 pears

Hence, Number of pears produced by B= 120 pears

Hence, the correct answer is 120 pears
