ruchis age was double that of niti 2 years ago,if ruchi was 2 years old to niti then how old is ruchi now​

Answer 1

Answer:

6 years

Step-by-step explanation:

ruchi age was double that of niti 2 years ago. if cthen how old is ruchi now?

Let say current age of Ruchi  = R Years

Then current age of Niti =  R - 2 Years (ruchi was 2 years older to niti )

2 years before

Ruchi Age = R - 2

Niti Age = R -2 -2 = R - 4

R - 2 = 2 ( R -4)   ( ruchi age was double that of niti )

R - 2 = 2R - 8

=> R = 6

if we say all data mentioned for ruchi is for current

Let say current age of Ruchi  = R Years

Then current age of Niti =  R - 2 Years (ruchi was 2 years older to niti )

2 years before

Niti Age = R -2 -2 = R - 4

R  = 2 ( R -4)   ( ruchi current age was double that of niti 2 years )

R  = 2R - 8

=> R = 8
