Question

If 40 percent of a number is subtracted from the secondnumber then the second number is reduced to its 3/5. Find the ratiobetween the first number and the second number.

​

Answer 1

SOLUTION :-

=>40 % of a number is subtracted from the second number then the second number is reduced to its 3/5.

=>We need to find the ratio between the first number and the second number.

Solution

=>Let us assume that the first number be “x” and the second number be “y”.

=>As per the given condition the equation becomes

=>40% of x = 3/5y

=>40/100x = 3/5y

=>2/5x = 3/5y

=>x/y = 2/5 × 5/3

=>x/y = 10/15

=>x/y = 2/3

Hence, The ratio between the two numbers is = 2 :3
