In the original ratio 9u : 2u we use u (unit) to represent. In the new ratio 10p : 1p we use p (part) to represent.
Thank you sir for the explanation
80+30 = 110
after
J:M:T = 10u : 1u : 11u
at first
J:M:T = 9u+90 : 2u+20 : 11u+110
for J
9u+90-80 = 10u ⇨ u = 10
for M
2u+20-30 = 1u ⇨ u = 10
(a)
9u+90 = $180 (Ans)
(b)
1u = $10 (Ans)
after
J:M:T = 10u : 1u : 11u
at first
J:M:T = 9u+90 : 2u+20 : 11u+110
for J
9u+90-80 = 10u ⇨ u = 10
for M
2u+20-30 = 1u ⇨ u = 10
(a)
9u+90 = $180 (Ans)
(b)
1u = $10 (Ans)
