- Bhanu has wine and water in ratio 5:2. If he sold 14(2/7)% of mixture and poured 15 litre of water in it so that new mixture becomes 10:9. Find the initial quantity of mixture?
50 L25 L49 L33 L40 LOption C

Let the quantity of wine and water be 5x and 2x resp.

[5x â€“ 5x/7]/[2x â€“ 2x/7 + 15] = 10/9

=> x = 7

Initial quantity of mixture = 7x = 7*7 = 49 L - A and B enter into a partnership with investment 3:8 and if ratio of time period investment of A and B is 4:3 resp. B gets Rs.750 more than A as profit share. Find the 40% of the total profit?
Rs.1000Rs.600Rs.800Rs.700Rs.900Option E

Let the investment of A and B be 3x and 8x resp.

Now,

8x*3 : 3x*4

= 2x : x

Difference

2x â€“ x = 750

=>x = 750

40% of profit = 750*3*2/5 = Rs.900 - Mr. Josh sold an article at a loss of 25% . If he has sold the same article Rs.130 more than he would have gained 40%. Find the cost price of the article?
200150320440220Option A

Let the CP be x.

SP = Rs.0.75x

Now,

40 = [0.75x + 130 â€“x ]/x*100

=> x = 200 - When a sphere is cut into two hemisphere the total surface area of two hemisphere is equal to the area of circle whose radius is equal to the side of square whose area is 144 cm^2. Find the radius of the sphere?
2(7)^1/2 cm4(2)^1/2 cm5(8)^1/2 cm2(6)^1/2 cm3(4)^1/2 cmOption D

Let the radius of the sphere be r cm.

r = (144)^1/2 = 12 cm

Let the radius of hemisphere be R cm.

3*pi*R*R + 3*pi*R*R = pi*r*r

=>R = 2(6)^1/2 cm - Karuna invested some amount in scheme P which offer 20% CI p.a. while some amount in scheme Q which offers 8% SI p.a. After 2 years ratio of interest earn from P to Q is 11:6. Amount invested by Karuna in scheme P is what percent of the amount invested by her in scheme Q.

55(5/7)%66(2/3)%68(3/5)%59(4/3)%61(2/5)%Option B

Let the amount invested in P and Q be x and y resp.

x*[(120/100)^2 – 1]/y*(8*2)/100 = 11/6

=>x/y = 2/3

Required% = 2/3*100 = 66(2/3)% - Tap A is 50% more efficient than Tap B. Both Tap together can fill the tank in (96/5) hours. Find the time taken by Tap A to fill the tank alone.

44 hours25 hours22 hours32 hours30 hoursOption D

Let the time taken by Tap A and B be x and x/1.5 hours resp.

1/x + 1/(x/1.5) = 1/(96/5)

=>x = 48

Time taken by Tap A= 48/1.5 = 32 hours - A vessel contains 540 litres mixture of honey, milk and water in the ratio of 3:4:5 resp. 15 litres of honey and 20 litres of milk is added to this mixture. Find the new ratio of honey, milk and water in the vessel.

3:10:76:8:92:8:56:5:73:6:9Option B

Quantity of honey in the vessel initially = [3/(3+4+5)]*540 = 135 L

Quantity of milk in the vessel initially = [4/(3+4+5)]*540 = 180 L

Quantity of water in the vessel initially = [5/(3+4+5)]*540 = 225 L

Required ratio = (135+15): (180+20): 225 = 6:8:9 - The interest earned on Rs.4800 at rate of R% compound annually is Rs.1008 after 2 years. What would be the simple interest earned on the same amount at the rate of (R+5)% per annum after 3 years?

Rs.2874Rs.2550Rs.2160Rs.1880Rs.2250Option C

Equivalent interest rate of 2 years = (1008/4800)*100 = 21%

R% + R% + (R^2/100)% = 21%

=> R = 10

Required interest = 4800*(10+5)% *3 = Rs.2160 - Find the time taken by a boatman to travel a distance of 250 km downstream where downstream speed of boatman is 250% of upstream speed of boatman. Speed of stream is 15 km/hr.
10 hours9 hours7 hours5 hours4 hoursOption D

Stream speed = 75/5 = 15 km/hr.

Speed of boatman be x km/hr.

Now,

(x+15) = 2.5(x – 15)

=> x = 52.5/1.5 = 35

Downstream speed of upstream = 35+15 = 50 km/hr.

Required time = 250/50 = 5 hours - Find the amount received by Sumit if he invested Rs.18,000 in a scheme offering 13% simple interest for 7 years.

Rs.38951Rs.35784Rs.34380Rs.33201Rs.32451Option C

Interest earned by Sumit = 18000*0.13*7 =Rs.16380

So, the amount received by Sumit after 7 years = 18000+16380 = Rs.34380 - If Govt. Charges Rs.10 from every Indian tourist and Rs.100 from every foreigner tourist, Find the total fare collected by Govt. In 2017 if number of Indian tourists were 27000?
Rs.30.5 lakhRs.25.9 lakhRs.34.8 lakhRs.35.7 lakhRs.30.1 lakhOption D

45% -> 27000

1% -> 600

55% -> 33000

Total fare collected = (27000*10) + (33000+10) = Rs.35.7 lakh - The number of Indian tourists in 2013 were what percent more or less than foreigner tourists in 2017?
14(2/17)%11(3/10)%17(5/14)%18(2/11)%15(3/13)%Option D

Required% = (65% – 55%)/55%*100 = 18(2/11)% - If in year 2012, 77000 foreigners visited Taj Mahal which was 10% more than those visited in year 2013, Find the total number of tourists in 2013?

4 lakh2 lakh6 lakh5 lakh3 lakhOption B

Let the total tourists in 2013 be x.

35/100*x*110/100 = 77000

=> x = 2 lakh - If Indians who visited Taj Mahal in 2015 was 21000, find the difference between number of foreigner tourists in 2015 and 2017 ?

30006000700040008000Option B

35% -> 21000

1% -> 6000

Required Difference = (65-55)*600 = 6000 - If Indian tourists in 2016 were 2250 more than Indian tourists in 2014. Find number of foreigner tourists in 2017?
91208250785465008110Option B

(55% – 40%) -> 2250

15% -> 150

55% -> 8250

Foreigner tourists in 2017 = 8250 - Number of Mouse’s produced in year 2011 was what percentage of total number of Motherboards produced in all the years together ?

30%20%40%60%70%Option B

Required% = 30/(30+35+15+25+45)*100 = 20% - What was the respective ratio between the number of Pen drives produced by company in the year 2011 and number of Mouses produced by the company in the year 2009 ?
1 : 27 : 95 : 82 : 37 : 5Option C

Req. ratio = 25000/40000 = 5 : 8 - What is the difference between the total number of Motherboards and Pen drives produced by company together in the year 2012 and number of Mouse’s produced by the company in 2008 ?

8066926075Option EReq. difference = ( 45 + 45 ) â€“ 15 = 75

- What was the respective ratio between the number of Mouse’s produced by the company in year 2009, 2011, 2012 ?
2 : 3 : 53 : 4 : 17 : 8 : 98 : 6 : 77 : 2 : 5Option D

Required ratio = 40000 : 30000 : 35000 = 8 : 6 : 7 - What is the percent increased in production of Motherboards in year 2011 from the previous year ?
44(5/6)%50(7/9)%66(2/3)%55(5/3)%61(2/5)%Option C

Required% increase = (25-15)/15*100 = 66(2/3)% - 313.31+116.31+62.03 = ? + 318.78
172165180192160Option A
