Question
Difference of two numbers is 1660. If 7.5% of the number is 12.5% of the other number, find the number?
Answer: Option B
- Let the numbers be a and b.
Then , 7.5 % of a =12.5% of b
a = 125 x b/75 = 5 x b/3.
Now, a - b =1660
5 x b/3 –b =1660
2 x b/3= 1660
b =[ (1660 x 3)/2] =2490.
One number = 2490, Second number =5 x b/3 =4150
