Question

the difference of two number is 15 . Half of the smaller number is greater than 1/5 of the greater number by 4 . find the numbers​

Answer 1

Answer:

let assume two numbers be x and y.

also assume x is greater than y.

then x-y=15

also

y/2 is greater than x/5 by 4.

so

y/2 - x/5=4

5y-2x=40

solving the two equations

x-y=15

5y-2x=40

multiplying eq 1 by 2 and then adding both eqn we get

2x-2y=30

5y-2x=40

3y=70

so y=70/3

and x=115/3
