Three-fourth of a number is equal to 60% of another number and the difference between the two numbers is 20. What is the sum of the two numbers?

a) 220 b) 180 c) 170 d) 320

• given 3/4x=60%y
  3/4x=3/5y
  after cancel 3
  5x=4y
  given x-y=20
  x=20+y
  sub x value
  5(20+y)=4y
  100+5y=4y
  y=100
  then sub y value in 5x=4y
  5x=4(100)
  5x=400
  x=400/5
  x=80
  now we got x and y values
  x=80 and y=100
  the sum of x and y is x+y=180
  the answer is (b) 180

• 3/4X=60/100Y
  X-Y=20
  ON SOLVING WE GET X+Y=220

• LET X,Y ARE NUMBERS
  3x/4 = 60y/100 ; x/y = 4/5 - 1 equ
  x-y = 20 - 2 equ divide 2 equ by y
  x/y - 1 = 20/y ; y = 100 x = 80 add both 180

• 3/4 *x=60/100 * y
  3/4*x=3/5*y
  5x=4y
  x-y=20
  x=20+y
  100+4y=5y
  y=100
  5x=400
  x=80
  sum of x qnd y is 180
