93. A company contracts to paint 3 houses. Mr.Brown can paint a house in 6 days while Mr.Black would take 8 days and Mr.Blue 12 days. After 8 days Mr.Brown goes on vacation and Mr. Black begins to work for a period of 6 days. How many days will it take Mr.Blue to complete the contract?
Answer: Option C
Explanation:Work done by Mr.Brown in 1 day = 1/6Â Work done by Mr Black in 1 day= 1/8Â Â Work done by Mr blue in 1 day= 1/12
Hence Acc to the question: 1/6*8Â 1/8*6 x*1/12= 3Â ( 3 because complete work is to paint 3 houses).
Solving this we get x= 11

94. A does 80% of a work in 20 days. He then calls in B and they together finish the remaining work in 3 days. How long B alone would take to do the whole work?
Answer: Option A
Explanation:Work done by A in 20 days = 80/100 = 8/10 = 4/5
Work done by A in 1 day = (4/5) / 20 = 4/100 = 1/25 --- (1)
Work done by A and B in 3 days = 20/100 = 1/5 (Because remaining 20% is done in 3 days by A and B)
Work done by A and B in 1 day = 1/15 ---(2)
Work done by B in 1 day = 1/15 – 1/25 = 2/75
=> B can complete the work in 75/2 days = 37 (1/2) days

98. Two boys and a girl can do a work in 5 days, while a boy and 2 girls can do it in 6 days. if the boy is paid at the rate of $28 a week. What should be the wages of the girls?
Answer: Option B
Explanation:2b+1g=1/5=>10b+5g=1---------(1)
1b+2g=1/6=>6b+12g=1---------(2)
from (1)&(2)
10b+5g=6b+12g
4b=7g
b:g=7:4
but above ratio is reverse b:g=4:7
wages of the girls=(4*28)/7
=4*4=16

99. If A alone does the work in 15 days,how much time will A and B take working together to complete the job,given that A is 30% more efficient than B?
Answer: Option B
Explanation:Ratio of times taken by A and B = 100 : 130
assume B takes x days to do the work.
So, 100:130::15:x
=> x=130*15/100=39/2.
B's 1 day's work=2/39
and A's 1 day's work=1/15
(A+B)'s 1 day's work=69/585
A & B together can complete the work in 585/69 days..
