Shantanu's 1 day's work = 1/2
Manu's 1 day's work =1/10
Shantanu's share : Manu's share =(1/12) : (1/10)Correct Option: A
Shantanu's 1 day's work = 1/2
Manu's 1 day's work =1/10
Shantanu's share : Manu's share =(1/12) : (1/10)
= (5/60) : (6/60)
= 5 : 6

A's 1 day's work = 1/9
B's 1 day's work = 1/15
A's share : B's share = (1/9) : (1/15)Correct Option: B
A's 1 day's work = 1/9
B's 1 day's work = 1/15
A's share : B's share = (1/9) : (1/15)
= (5/45) : (3/45)
= 5 : 3

A' s 1 day's work = 1/8
B' s 1 day's work = 1/10
∴ A' s share : B' s share
= 1/8 : 1/10 = 5/40 : 4/40 = 5 : 4
Let A' s share = 5k
and B' s share = 4k.
According to the question,
5k + 4k = 900Correct Option: B
A' s 1 day's work = 1/8
B' s 1 day's work = 1/10
∴ A' s share : B' s share
= 1/8 : 1/10 = 5/40 : 4/40 = 5 : 4
Let A' s share = 5k
and B' s share = 4k.
According to the question,
5k + 4k = 900
⇒ 9k = 900
∴ k = 100
∴ A' s share = 5k = 5 x 100 = ₹ 500
and B' s share = 4k = 4 x 100 = ₹ 400.
 A alone can do a piece of work in 3 days, while B alone can do the same work in 2 days. If they work together to complete the work, their total wages is fixed ₹ 225. Find the share of A.

A's 1 day's work = 1/3
B's 1 day's work = 1/2
A's share : B's share = 1/3 : 1/2 = 2/6 : 3/6
= 2 : 3Correct Option: A
A's 1 day's work = 1/3
B's 1 day's work = 1/2
A's share : B's share = 1/3 : 1/2 = 2/6 : 3/6
= 2 : 3
Share of A = (2/5) x 225 = ₹ 90
 P, Q and R enter into a contract for a piece of the work for ₹ 1100. P and Q together are supposed to do 7/22 of the work. How much does R get?

View Hint View Answer Discuss in Forum
Work done by (P + Q) = 7/22
Work done by R = 1  (7/ 22) = (227)/22 = 15/22
∴ (P + Q)'s share : R's share = (7/22) : (15/22)Correct Option: A
Work done by (P + Q) = 7/22
Work done by R = 1  (7/ 22) = (227)/22 = 15/22
∴ (P + Q)'s share : R's share = (7/22) : (15/22) = 7 : 15
R's share = (15/22) x 1100 = 15 x 50 = ₹ 750
