Ratio. Difference unchanged.
At 1st ratio K:L = 4:5 Difference =1
After ratio K:L = 2:5 Difference = 3
Make difference to the same as 3
At 1st, multiply by 3
K:L = 12:15 Difference =3
K:L = 2:5 Difference= 3 (after)
Before 12u - after 2u = 3000
10u = 3000
1u = 300
K at 1st
= 12u
= 12× 300
= $3600
After ratio K:L = 2:5 Difference = 3
Make difference to the same as 3
At 1st, multiply by 3
K:L = 12:15 Difference =3
K:L = 2:5 Difference= 3 (after)
Before 12u - after 2u = 3000
10u = 3000
1u = 300
K at 1st
= 12u
= 12× 300
= $3600
