The Ratio of Ages of Mona and Sona is 4:5. Twelve Years hence, their ages will be in the
ratio of 5:6. What will be Sonas age after 6 years ?
40 Years
50 Years
36 Years
66 years
Explanation:
Let their present ages be 4x & 6x
Then (4x + 12)/(5x + 12) = 5/6 or x=12
Sonas age after 6 years = (5x +6) = 66 years
Let their present ages be 4x & 6x
Then (4x + 12)/(5x + 12) = 5/6 or x=12
Sonas age after 6 years = (5x +6) = 66 years
