Question

the ages of rita and geeta are in the ratio of 5:7. ten years later,the ratio of their ages will be 7:9. find their present ages. [ hint: if their present ages are 5x and 7x years, then after 10 years, their ages will be (5x + 10) and (7x +10)​

Answer 1

Answer:

the ratio of 5: 7 is trn years of their ages

Answer 2

Answer:

suppose, their present ages are 5x and 7x.

then after 10 years, their ages will be (5x + 10) and (7x +10)

so, (5x+10)/(7x+10)=7/9

or, 49x+70=45x+90

or, 49x-45x=90-70

or, 4x=20

or, x=20/4=5

so, their present ages are 5×5=25 and 7×5=35.
