Question

SOLVE IT BY SIMULTANEOUS EQUATION

3 men and 4 boys can do a piece of work in 14 days while 4 men and 6 boys can do it in 10 days. How long would it take 1 boy to finish the work​

Answer 1

Answer:

let 1mans 1 days work = x

n 1boys 1 days work = y

so

3x + 4y = 1/14

4x + 6y = 1/10

after solving simultaneously, we get

x= 1/70 ,y= 1/140

so 1 boy would need 140 days to complete the work.
