1.	Three years ago the ratio of ages of Gargi and Supriya is 2 ∶ 1, also the present age of Gargi is 27 years more than Supriya. What is the sum of their present ages?1. 892. 683. 874. 935. 105
Answer» Correct Answer - Option 3 : 87 Given∶ Three years ago the ratio of ages of Gargi and Supriya is 2 ∶ 1 The present age of Gargi is 27 years more than Supriya. Calculations∶ Let the present ages of Gargi and Supriya be G and S respectively. According to question, \(\frac{{{\rm{G}} - 3}}{{{\rm{S}} - 3}} = \frac{2}{1}\) ⇒ 2S - G = 3 ---(1) Also, G = 27 + S ⇒ G -S = 27 ---(2) On solving the equations (1) and (2), We get, G = 57 and S = 30 ⇒ present age of Gargi = 57 years and the present age of Supriya = 15 years ⇒ Sum of their present ages will be; 57 + 30 = 87 years.

Answer» Correct Answer - Option 3 : 87

Given∶

Three years ago the ratio of ages of Gargi and Supriya is 2 ∶ 1

The present age of Gargi is 27 years more than Supriya.

Calculations∶

Let the present ages of Gargi and Supriya be G and S respectively.

According to question, \(\frac{{{\rm{G}} - 3}}{{{\rm{S}} - 3}} = \frac{2}{1}\)

⇒ 2S - G = 3 ---(1)

Also, G = 27 + S

⇒ G -S = 27 ---(2)

On solving the equations (1) and (2), We get, G = 57 and S = 30

⇒ present age of Gargi = 57 years and the present age of Supriya = 15 years

⇒ Sum of their present ages will be; 57 + 30 = 87 years.
