Question

3 numbers are in the ratio 2:5:7 if 7 is subtracted from the second number the resulting numbers form an arithmetic progression find the original numbers​

Answer 1

Step-by-step explanation:

let the original ratio be x.

Therefore,the ratio is 2x,5x and 7x respectively.

if 7 is subtracted from the second number.

Therefore, 2x+5x-7+7x=x

7x=x

: . x= 7

Therefore,substitute the value of x.

: . 2x=2(7)=14 degree

5x-7=5(7)-7=35-7=28 degree

7x=7(7)=49 degree
