Question

there were some birds and 1/4 of them went on tree and 1/5 of them went on pool and remaining 22 went to home . how many total where there at first.​

Answer 1

Step-by-step explanation:

let the total number of birds be x

number of birds went on tree=1/4x

number of birds went on pool=1/5x

remaining birds =22

a/q,

1/4x+1/5x+22=x

1/4x+ 1/5x - x/1 = -22

5x+ 4x- 20x/20 = -22

-11x/20 = -22

x= -22 ✖ 20/-11= 40

hence, total number of birds = 40
