Let the three ratio be P1, P2 and P3.
M, N, O invests in ratio 2:3:5
and their timing of investments are in the ratio 4:5:6
so we have to multiply invest ratio with their timings.
So,
P1:P2:P3=(2*4):(3*5):(5*6)
P1:P2:P3=8:15:30

Let one of the students secure x marks.
then, the other student secures (x+9) marks.
the sum of both their marks is equal to
56% of the sum of both means
56% of x+x+9 (x+9 obtained 56% marks when we both students marks)
or
(56/100)* x+x+9
so,
x+9=56% of (x+x+9)
x+9=(56/100)*(2x+9)
x+9=(112x+504)/100
100(x+9)=112x+504
100x+900=112x+504
900-504=112x-100x
396=12x
396/12=x
33=x
or
x=33
so the mark of other student will be
x+9
33+9
42
Marks obtained by both students are 33 and 42.

Let the number be x.
40% of a number means: (40/100) * x
20% of 650 means: (20/100)*650
by means = 190
So,
(40/100)*x is more than (20/100) * 650 means (40/100)*x is higher than (20/100)*650
Therefore,
(40/100)*x-(20/100)*650=190
40x/100-(20*650)/100=190
2x/5-130=190
2x/5=190+130
2x/5=320
2x=320*5
2x=1600
x=1600/2
x=800 (Answer)
