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

120 pears

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×
`(20)/(100)`= 144

`(100x+20x)/(100)`= 144

`(120x)/(100)`=144

x= 144×
`(100)/(120)`

x=120 pears

Hence, Number of pears produced by B= 120 pears

Hence, the correct answer is 120 pears
