Ronch [10]

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

Can someone please explain to me how to do this!? From 58 books to 65 books?

Inessa [10]

The way this question is worded is quite confusing. If all you have given is ‘58 books to 65 books’, maybe you mean a range? In that case the range would be 7. Or you could be talking about how many books it would take for 58 to get to 65. In this case, it would also be 7.
