Question

if two-fifths of a No added to 4 gives 36 find the number​

Answer 1

$\frac{2}{5} x + 4 = 36 \\ \frac{2}{5} x = 32 \\ x = 32 \times \frac{5}{2} \\ x = 80$

Answer 2

Answer:

x = 80

Step-by-step explanation:

let the number be 'x'

two-fifth of number=2/5

therefore, ATP

(2/5)x + 4 = 36

(2/5)x = 36 - 4

(2/5)x = 32

therefore x= (32×5)/2

x = 160/2

x = 80
