Question

the difference between two whole numbers is 66. The ratio of two numbers is 2 : 5. what are the two numbers

Answer 1

Let the two numbers be x & y...
By looking at the ratio we can say 2x = 5y...............(i)
By looking at the difference we can say x - y = 66....................(ii)

Or, x = 66+y.......(iii)
Putting this value of x in eq.(i) we get :
2(66+y) = 5y
132 + 2y = 5y
3y = 132
y = 44
Putting this value of y in eq.(iii) we get :
x = 66 + 44
x = 110

Answer 2

1 2 ka 4 4 2 ka 1.......
