Answers
Present ratio of ages between Supriya and her mother is 2: 9. ∴
Let the actual ages of Supriya and her mother be 2x and 9x. The age of her mother at the time of Supriya’s birth was 28 years. Therefore, the difference between Supriya and her mother's age will always remain 28 years.
∴ 9x – 2x = 28 ⇒ x = 4. Hence their present ages are 8 and 36 yrs.
Answer:
hiiiiii
your answer is here !
Step-by-step explanation:
Present ratio of ages between Supriya and her mother is 2: 9.
∴ Let the actual ages of Supriya and her mother be 2x and 9x.
The age of her mother at the time of Supriya’s birth was 28 years.
Therefore,
the difference between Supriya and her mother's age will always remain 28 years.
.
∴ 9x – 2x = 28
=> 7x = 28
=> x = 28/7
=> x = 4
⇒ x = 4.
Hence their present ages are 8 and 36 yrs.
