Question

the ratio of two numbers is 4to5 after adding 20 to the smaller number and subtracting 20 from the greater number the ratio becomes 14to13 find the number

Answer 1

Answer:

let smaller number be x

and larger be y

x:y=4:5

x/y=4/5

5x=4y

y=5x/4 ------>1

x+20:y-20=14:13

x+20/y-20=14/13

260+13x=35x-280

-22x=-20

x=10/11

put x=10/11 in equation 1

y=50/11 × 1/4

y=25/22
