Sir plz send the solution of 5, 2, and 10
ReplyDeletein 10.. a......c.....b
Deletec is in mid way,,
so equations will be
x/14+4 + (x/2)/14-4=38
x/18+x/20=38
20x+18x=38*20*18
x=360
2.(1-8/x)^4=16/81
ReplyDeleteX=24
8.6*10m+8*10w=26*2m+48*2w
ReplyDelete60m-62m=96w-80w
60-52*
8m=2w
8m=16w
1m=2w
now convert all into man
15m+20w 1m=2w 20w=10
and
6m+8w= 1m=2w 8w=4 6+4=10m
10m*10=25m*x x=4
