Difference of two numbers is 1660. If 7.5% of the number is 12.5% of the other number , find the number ?

A. 3456

B. 4156

C. 4150

D. 5678

Correct Answer : C.


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.
