SSC CGL 24th August 2021 Shift-1

10 years

12 years

15 years

8 years

Let's break down the statements:

- Silver anniversary means 25 years after marriage, and golden is 50 years after marriage.

- Sanju’s age 18 years after parents' marriage is x.

- At the golden anniversary (50 years after marriage), Sanju’s age would be (x + 32), because 50 - 18 = 32 more years.

- The ages' ratio at 18 years after marriage and at 50 years after marriage is 5 : 21.

- So, x / (x + 32) = 5 / 21.

- Cross-multiplied: 21x = 5x + 160 ? 16x = 160 ? x = 10.

- So Sanju was 10 years old 18 years after marriage, so he was born 8 years after marriage.

Option 4: 8 years
