uantitative Aptitude: Ages [Section 1 of 1] Q1 of 30 Marks 1 General Instructions 100% ×CloseTest time left: 32:55Select the correct answerRatio of present ages of P and Q are 7 : 3. After four years their ages will be in the ratio 2 : 1. Then the present age of P (in years) is?
Solution
Let's solve this step by step:
-
Let's assume the present ages of P and Q are 7x and 3x respectively.
-
According to the problem, after four years their ages will be in the ratio 2:1. So, we can write this as (7x+4)/(3x+4) = 2/1.
-
Solving this equation, we get 7x + 4 = 6x + 8.
-
Simplifying, we get x = 4.
-
So, the present age of P is 7x = 7*4 = 28 years.
