Question

Sushma is now 15 years older than Vijay but in 3 more years she will be 8 times as old as Vijay was 3 years ago . How old they are now? Plz explain in full working .

Answer 1

Step-by-step explanation:

let sushma age be x and vijay age be y

so, x=15+y

next equation

x+3=8(y-3)

substituting x=y+15 in second equation

y+18=8y-24

7y=42

Therefore y=7

Answer 2

Answer:

here is your answer friend

Step-by-step explanation:

let sushma's age be s years and let vijays age be v years

according to the question-

s=v+15  eq-1

after three years sushmas age=

s+3=8*(v-3)

s+3=8v-24

substituting the value of s from eq-1 we get

v+15+3=8v-24

8v-v=18+24

7v=42

v=42/7

v=6

so vijay's present age=v years=6 years

and sushma's present age=v+15=6+15=21 years

hope it helps

all the best for tomorrow
