Question

12. If 5 labourers earn 9000 in 15 days, how many labourers can earn ? 6720 in 8 days? ​

Answer 1

Answer: 7 labourers

Step-by-step explanation:

Given, 5 labourers earn  = 9000 in 15 days

Money earned 9000/- in a day=15*5

                    = 75

earnings of 1/- in a day=5*15/9000

                 = 1/120

earning of 1/- in 8 days=1/120*8

Hence, No.of labourers for 6720/- in 8 days=6720*1/120*8

                                                        = 672/96  

                                                        =7

7 labours can earn  6720/- in 8 days.
