At present, Kavita is twice Santa's age 8 yrs. Hence, the respective ratio between Kavita's and Sarita ages will be 22: 13. What is Kavita's present age? |
A) 26 yr
B) 18 yr
C) 42 yr
D) 36 yr
Correct Answer: D
Solution :
Let Sarita's present age \[=x\,\,yr\] |
Kavita's present age \[=2x\,\,yr\] |
According to the question, |
\[\frac{2x+8}{x+8}=\frac{22}{13}\] |
\[\Rightarrow \] \[26x+104=22x+176\] |
\[\Rightarrow \] \[4x=72\]\[\Rightarrow \]\[x=18\] |
Kavitas age \[=2\times 18=36\,\,yr\] |
