If `p : q=r : s=t : u=2:3,` then find `(m p+n r+ot):(m q+n s+ou)dot`

If p:q=r:s=t:u=2:3, then find (mp+nr+ot):(mq+ns+ou)

If p : q = r : s = t : u = 2 : 3, then (mp + nr + ot) : mq + ns + ou) is equal to :

m n o n o p q o p q r s------

In figure, if P Q_|_P S ,P Q|| S R ,/_S Q R=28^0 and /_Q R T=65^0, then find the values of x and ydot Figure

If m is the mean of p,q,r,s,t,u,v, then what is (p-m) + (q-m) + (r-m) + (s-m) + (t-m) + (u-m) + (v-m) equal to ?
