Question

the ratio of two numbers is 5:2 if 20 is subtracted from anticedent and 20 is added to consequent the ratio will be 3:4 find the sum of the number

Answer 1

the sum of the numbers is 280

Answer 2

let the first no be = 5x
then the other no =2x
after subtracting 20 from it =5x-20
after adding 20 in it = 2x+20
Then, 5x-20 / 2x+20=3/4
by cross multiply
4 (5x-20)=3 (2x+20)
20x-80=6x+60
20x-6x=60+80
14x=140
x=140÷14
x=10

then the first no will be 5x=50
second number = 2x=20
Sum of numbers = 50+20=70
So, your answer is 70
