A. 1200, 1800, 1600
B. 1000, 1200, 1500
C. 1600, 2400, 1800
D. 800, 1000, 1400

Solution of this Mcq

We will take the ratio of all three
Yaser:Hiba:Ali = 8 : 12 : 9
The sum of the ratio is: 29
Now
In order to take out Yaser’s share:
8*5800⁄29 = 1600
Simplified share of Yaser: 1600
Similarly, follow the same procedure for the rest of the two.

A. 70
B. 50
C. 40
D. 60

Solution to This Mcqs:

Amount of work done by A and B in 1 day = 1/30
Amount of work done by A and B in 20 days = 20 × (1/30) = 20/30 = 2/3
Remaining work – 1 – 2/3 = 1/3
A completes 1/3 work in 20 days
Amount of work A can do in 1 day = (1/3)/20 = 1/60
A can complete the work in 60 days

A. 12
B. 15
C. 22
D. 20

Brief Fact About Mcq

Work done by P in 1 day = 1/15
Work done by Q in 1 day = 1/10
Work done by P and Q in 1 day = 1/15 + 1/10 = 1/6
Work done by P and Q in 2 days = 2 × (1/6) = 1/3
Remaining work = 1 – 1/3 = 2/3
Time taken by P to complete the remaining work 2/3 = (2/3) / (1/15) = 10 days
Total time taken = 2 + 10 = 12 days
