Mr. Sher employed some painters and plumbers for his construction site. A plumber was paid $5 a day and a painter was paid $14 a day. Given that he employed 5 times as many painters as plumbers and a total of $300 was paid to these workers for the day, how many less painters than plumbers did Mr. Sher employ for his site?

Number of plumbers = 1 u
Number of painters = 5 x 1 u = 5 u
Total amount paid
= (5 u x 14) + (1 u x 5)
= 70 u + 5 u
= 75 u
75 u = 300
1 u = 300 ÷ 75 = 4
Number of less plumbers than painters
= 5 u - 1 u
= 4 u
= 4 x 4
= 16
Answer(s): 16
