5/8-1/2= 1/8 {as we need half milk ratio},,, 2/5-1/2=1/10 {as we need half },,, so new ratio is 1/8:1/10 => 5:4

2Rs:5Rs:7Rs.
so, No. of coins in ratio 2:10:28
=1:5:14
Now multiplying this ratio by 20, we get 20:100:280.. sum of this is 400.. ie 400 coins.. so sum of values of these coins is 20+50+70=140
