The length of the originalsheet of paper is(a) 13 units(b) 15 units(c) 16 units(d) 30 units​

Answer»

Answer:

Step-by-step explanation:

Let LENGTH of 3 pieces be x,y,z respectively

So total length=x+y+z

Now x=3+5+7/3=5

So,y=x+z/3

=>3y=3x+z

=>3y=15+z......(1)

ALSO,z=x+y......(2)

PUT eq.(2) in eq.(1)

So 3y=15+x+y

=>2y=20

=>y=10

From eq.(1)

z=10+5=15

So Total length is x+y+z=5+10+15=30units
