Answer:
12 Days
Explanation:
A certain sum of money is sufficient to pay either A's wage for 20 days or B's wages for 30 days. For how long will it suffice if both A and B work together
Let Say Amount = 60M
sufficient to pay A's wage for 20 days
=> A's Wage per Day = 60M/20 = 3M
sufficient to pay B's wage for 30 days
=> B's Wage per Day = 60M/30 = 2M
Let say It is sufficient for D days
Thne 3M*D + 2M*D = 60M
=> 5MD = 60M
=> D = 12
It is Sufficent for 12 Days
