Question

renu is 6 years older than her younger sister. After 10 yearsthe sum of their ages will be 50 years. find the number

Answer 1

Answer:

renu=18 year

sister=12 year

Answer 2

Answer: Renu's present age=18 years

renu's younger sister's age=12 years

Step-by-step explanation: let the present age of renu's younger sister be x

renu's present age=x+6

after 10 years,

renu's sister's age=x+10

renu's age=(x+6)+10

sum of their age=50

that is,(x+10)+(x+16)=50            : [(x+6)+10=x+16]

2x+26=50

2x=50-26

2x=24

x=12

therefore,Renu's  younger sister's present age is 12

and Renu's present age is x+6=12+6=18
