303:403301:399291:400301:408307:403Option D
Required ratio = 10836:14688 = 301:408 - Find the difference between the number of English newspapers sold by firm C in Delhi and the number of English newspapers sold by firm C in Lucknow.
32224100333332253200Option D
Required difference = 21285 – 18060 = 3225 - Find the percentage of the total number of Hindi newspapers sold by firm D in both cities together with respect to the total number of newspapers sold in both cities.
62%40%58%49%50%Option C
Required% = [28210+24820]/[54250+36500]*100 = 58.4% == 58% - Find the difference between the numbers of Hindi newspapers sold by firm A in Lucknow and the numbers of Hindi newspapers sold by firm B daily in Lucknow.
55505000578054605985Option D
Required difference = 17460 – 12000 = 5460 - Find the average number of English newspaper sold each firm in Lucknow.
1125010952112501000021500Option B
Required average = (6750+6790+18060+11680+11480)/5 = 10952 - A shopkeeper marks up an item of cost price Rs.1800 by (x+2)% and sells it at a discount of (x-3)% and in the whole transaction, he makes neither profit nor loss. Find the value of x.
1020151223Option E
MP = 1800*(100+x+2)% = 18(102+x)
SP = MP – Discount = 18(102+x) – 18(102+x)*(x-3)% Now, 18*(102+x){1-(x-3)% } – 1800 = 0
=> (102+x){1-(x-3)%} = 0
=>x^2 – x -506 = 0
=> x^2 – 23x + 22x – 506 = 0
=> x = 23 - The ratio of the number of males and females in a company is 9:5 resp. If the number of males is increased by (x+10)% and the number of females is increased by (x+5)%, then the ratio of males and females in the company becomes 15:8 resp. Find the value of x.
1110151213Option C
[9*(100+x+10)%]/[5*(100+x+5)%] = 15/8
=> [3*(110+x)]/[5(105+x)] = 5/8
=> x = 15 - A 240 m long train can cross a platform of 319 m in 43 seconds. If ‘x’ new number of bogies of length 69 m each are attached to the train, then the train will be able to cross a man standing on the platform in 45 seconds. Find the value of x.
26543Option C
[240+319]/speed = 43
=>speed = 13 m/s Also, [240+x*69]/13 = 45
=> x = 5 - The average weight of a class of (x+6) students is (x+1) kg. If 7 new students of average weight (x+7) kg join the class, the average weight of the class is increased by 0.7 kg. Find the value of x.
3047364446Option B
Total weight of the class = (x+6)*(x+1) kg
Weight of new students = 7*(x+7) kg
Now, [(x+6)(x+1)+7(x+7)]/[(x+6)+7] = (x+1)+0.7
=> x = 47 - In a 1000 m race , A beats B by 100 m and A beats C by 200 m or 50 seconds. Find the speed of B.
4.7m/s6.2 m/s3.2 m/s4.5 m/s5.5 m/sOption D
1000/A = (1000-100)/B => A:B = 10:9 And 1000/A = (1000-200)/C
=> A:C = 5:4
So, A:B:C = 10:9:8 1000/A = 1000/C -50
=> 1000/(10/8)C = 1000/C – 50
=> C = 200/50 = 4 m/s
Speed of B = 9/8*4 = 4.5 m/s
