Explanation:
Ratio of the wages of A, B and C = 5 : 6 : 4
A's share : B's share : C ' share
= (6 x 5) : (4 x 6) : (9 x 4)
=30 : 24 : 36 = 5 : 4 : 6
? A's share = (5/15) x 1800 = ? 600
Correct Answer: ? 900
Explanation:
1 day's work of Amit = 1/12
1 day's work of Vipul = 1/16
1 day's work of Kapil = 1/24
Amit's share : Vipul's share : Kapil's share
= (1/12) : (1/16) : (1/24) = 4/48 : 3/48 : 2/48 = 4 : 3 : 2

=3 x 300 = ? 900

Explanation:
A's 1 day's work = 1/21
B's day's work = 1/28
? Same money is sufficient to pay the wages of both for
= 1 / [(1/21) + (1/28)] = (21 x 28) / (21 + 28)

= 3 x 4 = 12 days
Correct Answer: ? 80
Explanation:
Vandana's 1 day's work = 1/10
(vandana + Ruchi)'s 1 day work =1/6
? Ruchi's 1 day's work
= 1/6 - 1/10 = (10 - 6)/ (6 x 10) = 4 / 60 = 1/15
? Vandana's share : Ruchi's share
= 1/10 : 1/15 = 3/30 : 2/30 = 3 : 2
Ruchi's share = 2/5 x 200 = ? 80
Correct Answer: ? 720
Explanation:
A's 1 day's work = 1/2
B's 1 day's work = 1/3
A's share : B's share = 1/2 : 1/3 = 3/6 : 2/6 = 3 : 2
A's share (3/5) x 6000 = 3 x 1200 = ? 3600
? 20% of A's share 3600 x (20/100) = ? 720

Received wages = 12(50 - x) - 6x = 420
? 600 - 12x - 6x = 420
? 18x = 600 - 420 = 180
? x = 180/18 = 10 days
