Question

It takes a total of 475 seconds for one technician to assemble one airrules smart phone, working alone. however, airrules manufactures its smart phones with twenty technicians staffing a twenty station assembly line, producing one smart phone every 30 seconds. how efficient is the airrules smart phone assembly line?

Answer 1

Normally if one tecnician takes 475 seconds to assemble one air rule smartphone. Then it would take. 20 technicians X secs to do the same So It would take 20 tecnicians X secs = (20 * 475) / 1 = 9500 secs. I. e it takes 20 technicians 9500 secs to manufacture a smartphone. But airrules uses 20 technicians to manufacture the same phone in only 30 secs. So its efficiency would be: Number of secs it takes the 20 techician to manufacture the phone * efficiency = Normal of hours it would usually take 20 techician to manufacture the phone. So we have 30 * X = 9500 X = 9500/30 = 316.777. So they are 316.667 times as efficient.
