Final answer:
Ramesh will take 76 minutes to iron 16 shirts.
Step-by-step explanation:
To find out how long Ramesh will take to iron 16 shirts, we need to multiply the time it takes to iron one shirt by the number of shirts. Ramesh takes 19/4 minutes to iron one shirt. So to find the total time, we multiply 19/4 by 16.
19/4 x 16 = 76 minutes.
Therefore, it will take Ramesh 76 minutes to iron 16 shirts.
