of Mr Rao three times that of his daughter ?​

Answer 1

Answer:

2.5 yr

Step-by-step explanation:

Current age of MR.Rao = 50 yr

Current age of Sowjanya = 20 yr

Let assume that, after x year , age of Mr. Rao will be 3 time her daughter

so,

50+ x = 3(20 + x)

50 + X = 60 + 3x

X = 10/4 = 2.5 yr

Answer 2

CURRENT AGE OF MR.RAO=50 YEARS

CURRENT AGE OF SOEJANYA =20 YEARS

SO ACORRDING TO THE QUESTION,

50+X=3(20+X)

50+X=60+3X

2x=10

x=10/2=5YEARS
