Question

riya is now 2 years old and ravina is 24 years old . In how many years will Ravina be three times old as Riya​

Answer 1

Answer:

after -18 years

Step-by-step explanation:

Answer 2

Let Riya’s age be x.

Let her mother’s age be y.

Given:

y=4x . . . . . (i)

y+5=3(x+5) . . . . . (ii)

Solution:

Use the relation obtained in (i) and substitute it in eq. (ii).

So, we get

y+5=3(x+5) replaced by

this

4x+5 = 3 (x+5)

⇒ 4x + 5 = 3x + 15 ……………………….(Using the basic algebraic solving rules)

sorting variable to the L.H.S and constants to the R.H.S,

4x - 3x = 15 - 5

⇒ x = 10

∵ y=4x

∴ y = 4 x 10 = 40

∴ y = 40

Conclusion:

Riya is currently 10 years old, while her mother is 40 years old.
