Question

if rupees 1440 is divided into two parts in which one part is 7 9th of the second then the smaller part is

Answer 1

Let the larger part = x

Then, the smaller part =7x/9

Therefore,

x+7x/9=1440

16x/9=1440

16x=1440 X 9

x=(1440 X 9)/16

x=810

 

Therefore, the smaller part is 7x/9= 7*810/9= Rs 630

Answer 2

the answer is 18
1440=X+Y....eq-1
X=79Y....eq-2
substituting X=79Y in equation 1
1440=X+79X
1440=80X
X=1440/80
X=18rs
