Shikha is 3 years younger to her brother Ravish. If the sum of their ages 37 years, what are their present age? |
|
Answer» Let the present age of Shikha be x years. Therefore, the present age of Shikha’s brother Ravish = (x + 3) years. So, sum of their ages = x + (x+ 3) ⇒ x +(x + 3) = 37 ⇒ 2x + 3 = 37 Subtracting 3 from both sides, we get ⇒ 2x+ 3 – 3 = 37 – 3 ⇒ 2x = 34 Dividing both sides by 2, we get ⇒ 2x/2 = 34/2 ⇒ x = 17 Therefore, the present age of Shikha = 17 years, And the present age of Ravish = x + 3 = 17 + 3 = 20 years. |
