Answer 1

Answer:

hlo

your answer is here !

Step-by-step explanation:

Let age of Romi be y

Nisha is 15 years elder than Romi = (y + 15).

So Nisha's age 5 years ago = (y + 15 – 5).

Romi's age before 5 years = (y – 5)

5 years ago,

Nisha is 3 times as old as Romi

(y + 15 – 5) = 3 (y – 5)

(y + 10) = (3y – 15)

2y = 25

⇒ y = 12.5

Romi's age = 12.5 years

Nisha's age = (y + 15) = (12.5 + 15) = 27.5 years.

Answer 2

Sᴏʟᴜᴛɪᴏɴ :-

Let us assume That, Nisha Present age is = x Years.

Than,

→ Romi Present age = (x - 15) Years.

So,

→ 5 Years, ago , Nisha was = (X - 5) years old.

→ 5 Years, ago , Romi was = (x - 15) - 5 = (x - 20) Years old.

A/q,

→ Nisha 5 Years ago = 3 * Romi 5 Years ago .

→ (x - 5) = 3(x - 20)

→ x - 5 = 3x - 60

→ x - 3x = -60 + 5

→ (-2x) = (-55)

→ x = 27.5 Years. (Ans).

Hence, Nisha Present age is 27.5 Years.
