A) 9 years
B) 15 years
C) 3 years
D) 5 years
Correct Answer: A
Solution :
Ratio of present ages of Sonali and Monali \[=5:3\] After 5 years ratio of ages of both girls =10:7 Let actual present ages are 5x and 3x years. \[=\frac{5x+5}{3x+5}=\frac{10}{7}\] \[=35x+35=30x+50\] \[5x=15\] \[x=3\] So, Monali age \[=3\times 3=9\]yearsYou need to login to perform this action.
