Question

divide rupees 90 into two parts so that the ratio between their difference and sum 1 ratio 9

Answer 1

Answer.  40 and 50. 

Solution 

Let  x  be the smaller of the two parts. 

Then the other part is  90-x. 

Notice that the sum of these parts is precisely  90,  while the difference is  (90-x) - x = 90-2x. 

Then,  according to the condition, 

 = ,       -----> 

 = , 

90 - 2x = 10, 

2x = 90 - 10 = 80, 

x =  = 40. 

Thus the smallest part is  40,  and the other part is  90-40 = 50. 

Answer 2

Answer:

40 and 50

Step-by-step explanation:

Let 2 parts be x and 90-x

x-90-x:x+90-x::1:9

2x-90/90=1/9

2x-90=10

2x=100

x=50

One number is 50

Other number is 90-50=40

Therefore, two numbers are 40 and 50
