Question

10 year ago a's age was half of the b's age if the ratio of their present age is 3:4 what will be the sum of their present age ​

Answer 1

HLO GUYS,.

______________________________

let the present age of A be 3x and that of B be 4x

10 years ago

A's age would have been 3x-10

B's age would have been 4x -10

now accoding to question A's age was half of B 's age

so,

2(3x-10)=4x-10

6x-20=4x-10

2x=10

x=5

so present age of A = 3x = 15

present age of B = 4x = 20

sum of there present age = 20+15=35

HOPE IT'S HELP YOU!!!!
