Question

A certain sum of money is sufficient to pay either georges wages for 15 days or marks wages for 10 days. For how long will it suffice if both george and mark work together?

Answer 1

ANSWER

Let the sum be x & no of days be n, then George wage per day would be x/15

& similarly x/10

so,

=)x/15+ x/10

=)2x+3x/30

=) 5x/30

=) x/6

Now,

n× x/6 = n= 6

Hence, work together in 6 days
