Question

A person have notes of 100, 50 and 10 and the are inthe formof ration, 2:3:5 and total amount is 400000 find number of notes

Answer 1

Let 100 rupees note = x

-----50------------------- = y

-----10---------------------= z

A.T.Q.

2x=3y=5z ...(1)

and, 100x+50y+10z=400000

50(3y) + 50y + 2(3y) = 400000

150y + 50y + 6y = 400000

206y = 400000

y = 200000/103

therefore,

x = 300000/103, y = 200000/103

And, z=120000/103
