Question

Ratna's age is 3 years more than twice the age of kripa and 5 years more than 3 times the age of Nisha. If kripa's age is 3 years more than age of Nisha. How old are Ratna and Nisha

Answer 1

Answer:

Ratna = 17

Kripa=7

Nisha=4

Step-by-step explanation:

Let Kripa be K and Nisha be N

It is given that-

Ratna's age = 2K +3 = 3N+5

Next, it is given that Kripa's age is N+3

So, in the first equation in place of 2K we can write- 2(N+3) so as to make the equation same from both sides...

So, the new equation= (2N+6)+3=3N+5

=6+3-5=3N-2N

=4=N

So, Nisha's age is 4.

So, Kripa's age is N+3=4+3=7.

And Ratna's age is 3N+5= 3*4+5=17.
