Difference of two numbers is 1660. If 7.5% of the number is 12.5% of the other number , find the number ?
3456
4156
4150
5678
C. 4150
Let the numbers be x and y. Then , 7.5 % of x =12.5% of y
X = 125*y/75 = 5*y/3.
Now, x-y =1660
5*y/3 –y =1660
2*y/3= 1660
y =[ (1660*3)/2] =2490.
One number = 2490, Second number =5*y/3 =4150.
