arithmetic - one year ago the ratio of vikrams and pramods age was 6 7 respectively four years hence this ratio would becomes 7 8 how old is pramod - skillgun

Solution: let Vikram's and Pramod's ages one year ago be 6x and 7x respectively. Then, Vikram's age 4 years hence = (6x+1)+4=(6x+5) years.
Pramod's age 4 years hence =(7x+1)+4=(7x+5) years.
6x+5 7
------- = ---- <==> 8(6x+5)=7(7x+5) <==> x = 5.
7x+5 8
Hence, Pramod's present age=(7x+1) = 36 years.
