wood showed that 32% were oak
trees, 26% were birch trees and
the remainder were pine trees.
How many pine trees were there?​

Answer 1

Answer:

105 Pine Trees

Given that :

Total trees = 250

Of which

32% are oak trees

26% are birch trees

Remaining are pine trees

To find :

Number of pine trees

Step by step solution :

1: Percentage of pine trees

32% + 26% = 58%

100% - 58% = 42%

2: Number of pine trees

42% of 250

42/100 × 250

42/10 × 25

21/5 × 25

21 × 5

105

Hence, the number of pine trees is 105.

Answer 2

Answer:

105

Step-by-step explanation:

Percentage of oak tree = 32%

Percentage of birch tree =26%

So,

Oak tree = 32×250/100 =80

Birch tree = 26×250/100 =65

So,

=250-(80+65)

=250-145

=105
