Question

In a orchad of 400 trees 35 % are mango 42 % are apple trees and the rest were grape vines how many grape vine are these

Answer 1

Answer:

Grape vines = 92

Step-by-step explanation:

Total tress = 400

Mango tress = 35% of 400

Mango tress = $\dfrac{400 \times 35}{100}$

                     = 35×4

Mango tress = 140

Apple tress = 42% of 400

                   = $\dfrac{400 \times 42}{100}$

                   = 4×42

Apples tress = 168

But Mango trees + Apple tress + Grape vines = 400

140 + 168 + Grape vines = 400

308 + Grape vines = 400

Grape vine = 400 - 308

Grape vines = 92
