  1. If p : q = r : s = t : u = 2 : 3, then (mp + nr + ot) : (mq + ns + ou) equals :
    1. 3 : 2
    2. 2 : 3
    3. 1 : 3
    4. 1 : 2
Correct Option: B

p
=
r
=
t
=
2
qsu3

p
=
q
= k
23

⇒ = 2k, q = 3k
Similarly, r = 2k, s = 3k, t = 2k, u = 3k
Now
mp + nr + ot
=
m.2k + n.2k + o.2k
mq + ns + oum.3k + n.3k + o.3k

=
2k(m + n + o)
=
2
or 2 : 3
3k(m + n + o)3
