Question

Asha is five year older than robot 5 year ago Asha was twice as old robot was then find their present ages

Answer 1

Let Asha's age be x and her robot's age be y.

According to question, Asha is five year older than robot; which is numerically                   x=y+5----(1)

Now, 5 years ago, Asha's age would have been (x-5) yrs and her robot's (y-5) yrs.

A/Q,

$(x-5)=2(y-5) => x-5=2y-10=>x=2y-5$-----(2)

Equating (1) and (2), we get:

y=10, therfore Asha's present age is 15 .

Answer 2

Answer:

Present age of Asha = 15 years and present age of Robert = 10 years

Step-by-step explanation:

Let present age of Asha be x years

and present age of Robert be y years

Therefore, x = y + 5

or x – y = 5 ...(1)

5 years ago, Asha was x – 5 years and Robert was (y – 5) years old.

Therefore, x – 5 = 2(y – 5)

or x – 2y = – 5 ...(2)

Solving (1) and (2), we get y = 10 and x = 15

Hence, present age of Asha = 15 years and present age of Robert = 10 years
