Answer 1

Answer:

The number of boys in a class of 45 students where their percentage is 60 is 27.

The number of mango trees in the orchard of 400 trees when their percentage is 35 is 140.

Step-by-step explanation:

Total number of students in the class = 45

Percentage of boys in the class = 60

∴ The number of boys in the class = $\frac{60}{100} \times 45$

                                                         = 27.

Total number of trees in the orchard = 45

Percentage of mango trees in the orchard = 60

∴ The number of mango trees in the orchard = $\frac{35}{100} \times 400$

                                                                           = 140.
