Question

6. The ages of Shailu and Shalini are in the ratio 5:7. Four years later, their
ages will be in the ratio 3:4. Find their present ages,​

Answer 1

Step-by-step explanation:

(5x+4 )/(7x+4)=3/4

=(7x+4)×3=(5x+4)×4

=21x+12=20x+16

=21x-20x=16-12

=x=4

shailu present age=3×4=12 year

Shalini present age=4×4=16 year
