Answer 2

12 Men Get ₹4200 When They Work 30 days

Let Each Days 12 men get=₹x

Then In 30 days 12 men get=₹30x

Given Wage=4200 for 30 days

30x=4200

x=4200/30

x=140

Means 12 men Get Each Day=x=₹140

Then 1 man in 1 day=140/12

=₹35/3

1 man in 1 day=₹35/3

Now 18 men Work work 24 days

18 men in one day we get=18×35/3

=₹210

Means 18 men get ₹210 in 1 day

Then in 24 days

=210×24

=₹5040

Hence Option (a) is Right

Answer=₹5040
