Arjun is twice as old as shriya. If 5 years ago his age was 3 times shriya s age ,then what is arjun s present age?
prisoha [69]

Answer:

20

Step-by-step explanation:

Let Shriya's current age b <em>x</em><em>.</em><em> </em>Arjun's current age will be <em>2</em><em>x</em>.

5 years ago, Arjun's age was <em>2</em><em>x</em><em>-</em><em>5</em><em> </em>and Shriya's age was <em>x</em><em>-</em><em>5</em><em>.</em>

Since Arjun's age was 3 times Shriya's age 5 years ago,

<em>2</em><em>x</em><em>-</em><em>5</em><em> </em>= <em>3</em><em> </em><em>(</em><em>x</em><em>-</em><em>5</em><em>)</em>

<em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>0</em>

<em>2</em><em>x</em><em> </em><em>=</em><em> </em><em>2</em><em>0</em>
