Question

Make two parts of 135 such that one part is four-fifth of the second part. Calculate both
the parts

Answer 1

Answer:

The two parts are 60 and 75

Step-by-step explanation:

Let the two parts be x and y

so, x+y=135

¾ of one part is equal to ⅗ oh other parts .

¾(x) =⅗(y )

x/4 =y/5

x/y = 4/5

Adding 1 on both sides

x/y+1 = 4/5+1

(x/y)/y = 9/5

135 /y=9/5

y= 135×5/9

y= 75

x+y= 135

x+75=135

x= 135-75

x=60
