Question

Two numbers are in the ratio of 5:8 if 12 be added to each they bacame in the ratio of 3:4 the product of two numbers is

Answer 1

Step-by-step explanation:

x:y=5:8

8x/5=y..(1)

(x+12)÷(y+12)=3/4

4x+48=3y+36

12=3y-4x

12= 3(8x/5) -4x ....from (1)

24x-20x=12(5)

4x=60

x=15...(2)

put (2) in (1)

y=8(15)÷5

y=24

product=xy= 24×60= 1440
