The pie chart shows expenditure incurred by a family on various items and their savings.
If the expenditure on education is Rs 1600 more than that of housing then the expenditure on food is
Correct
Explanation:
(70/360)*x = (54/360)*x + 1600
Solve, x = 36000
So exp on food is = (120/360)*36000 = 12000Incorrect

1 pointsCategory: Quantitative AptitudeA man rides at the rate of 18 km/hr but stops for 6 minutes to make drink water to horse at the end of every 7th km. What is the time taken to cover 90 km this way?
Correct
Explanation:
In 90 km, 90/7 = 12
So number of stoppages = 12
So total time is (90/18) hrs + 12*6 mins = 5 hrs + 72 mins = 6 hrs 12 minsIncorrect
Explanation:
In 90 km, 90/7 = 12
So number of stoppages = 12
So total time is (90/18) hrs + 12*6 mins = 5 hrs + 72 mins = 6 hrs 12 mins

1 pointsCategory: Quantitative Aptitude15 litres of a mixture contains milk and water in the ratio 4 : 1. If 3 litres of milk is mixed in it, the percentage of water in the new mixture will be
Correct
Explanation:
4 : 1, so In 15 l mixture, milk is (4/5)*15 = 12 and then water = 3 l
3 l of milk added, so total mixture = 15+3 = 18 l, and water remained at 3l
So % of water is (3/18)*100Incorrect
Explanation:
4 : 1, so In 15 l mixture, milk is (4/5)*15 = 12 and then water = 3 l
3 l of milk added, so total mixture = 15+3 = 18 l, and water remained at 3l
So % of water is (3/18)*100

1 pointsCategory: Quantitative AptitudeA fruit seller buys some oranges at the rate of 4 for Rs 10 and an equal number at 5 for Rs 10. He sells the whole lot at 9 for Rs 20. What is his gain/loss%?
Correct
Explanation:
We have a shortcut for this:
Bought 4 for Rs 10 and 5 for Rs 10.
Sold 9 for Rs 20 or (9/2) for Rs 10. Now all bought and sold at Rs 10. Remember the price should be same in all cases.
Gain/loss% =
So gain/loss% =[ 2*4*5/[(9/2) * (4+5)] – 1] * 100 = [80/81 – 1] * 100 = – 100/81
– means loss, 100/81%Incorrect
Explanation:
We have a shortcut for this:
Bought 4 for Rs 10 and 5 for Rs 10.
Sold 9 for Rs 20 or (9/2) for Rs 10. Now all bought and sold at Rs 10. Remember the price should be same in all cases.
Gain/loss% =
So gain/loss% =[ 2*4*5/[(9/2) * (4+5)] – 1] * 100 = [80/81 – 1] * 100 = – 100/81
– means loss, 100/81%

1 pointsCategory: Quantitative AptitudeA man rows down a river 15 km in 3 hrs with the stream and returns in 7 ½ hrs. The rate at which he rows in still water is
Correct
Explanation:
Downstream speed = 15/3 = 5
Upstream speed = 15/(15/2) = 2
So speed in still water is (5+2)/2 = 7/2Incorrect
Explanation:
Downstream speed = 15/3 = 5
Upstream speed = 15/(15/2) = 2
So speed in still water is (5+2)/2 = 7/2

1 pointsCategory: Quantitative AptitudeIf (tan ɸ + cot ɸ)/ (tan ɸ – cot ɸ) = 2, then find the value of sin ɸ. (0 ≤ ɸ ≤ 90)
Correct
Explanation:
Do componendo and dividend
(tan ɸ + cot ɸ + tan ɸ – cot ɸ)/ (tan ɸ + cot ɸ – (tan ɸ – cot ɸ)) = (2+1)/(21)
Gives 2 tan ɸ/2 cot ɸ = 3
Solve, (sin ɸ/cos ɸ) * (cos ɸ/sin ɸ) = 3
So sin^{2} ɸ = 3cos^{2} ɸ
Or sin^{2} ɸ = 3 ( 1 – sin^{2} ɸ)
Or 4 sin^{2} ɸ = 3
Gives sin^{2} ɸ = 3/4
So sin ɸ = √3/2Incorrect
Explanation:
Do componendo and dividend
(tan ɸ + cot ɸ + tan ɸ – cot ɸ)/ (tan ɸ + cot ɸ – (tan ɸ – cot ɸ)) = (2+1)/(21)
Gives 2 tan ɸ/2 cot ɸ = 3
Solve, (sin ɸ/cos ɸ) * (cos ɸ/sin ɸ) = 3
So sin^{2} ɸ = 3cos^{2} ɸ
Or sin^{2} ɸ = 3 ( 1 – sin^{2} ɸ)
Or 4 sin^{2} ɸ = 3
Gives sin^{2} ɸ = 3/4
So sin ɸ = √3/2

1 pointsCategory: Quantitative AptitudeThe angles of elevation of the top of a building and the top of the chimney on the roof of eth building from a point on the ground are x and 45 degree respectively. The height of the building is h metre. Find the height of the chimney in metre.
Correct
Explanation:
AB = h, let AD = y = chimney height
In ∆BCD, tan 45 = BD/BC
So 1 = (h+y)/BC, or BC = h+y
In ∆ABC, tan x = AB/BC
SO tan x = h/BC, so BC = h cot x
Solve both equations, y = h cot x – hIncorrect
Explanation:
AB = h, let AD = y = chimney height
In ∆BCD, tan 45 = BD/BC
So 1 = (h+y)/BC, or BC = h+y
In ∆ABC, tan x = AB/BC
SO tan x = h/BC, so BC = h cot x
Solve both equations, y = h cot x – h

1 pointsCategory: Quantitative AptitudeBy selling 1500 articles, there is a loss of equal to the cost price of 100 articles. Find the loss%.
Correct
Explanation:
Loss is there, so CP – SP
CP of 1500 articles – SP of 1500 articles = CP of 100 articles
So CP of 1400 articles = SP of 1500 articles
So loss% = (15001400)/1500 * 100 = (100/1500)*100Incorrect
Explanation:
Loss is there, so CP – SP
CP of 1500 articles – SP of 1500 articles = CP of 100 articles
So CP of 1400 articles = SP of 1500 articles
So loss% = (15001400)/1500 * 100 = (100/1500)*100

Explanation:
Let unknown number be x
So the new number becomes = 71*x + 47
Now this number is divisible by 7 giving the quotient 98, so the number should be 7*98
So 71*x + 47 = 7*98
Solve, x = 9, which is a multiple of 3Incorrect
Explanation:
Let unknown number be x
So the new number becomes = 71*x + 47
Now this number is divisible by 7 giving the quotient 98, so the number should be 7*98
So 71*x + 47 = 7*98
Solve, x = 9, which is a multiple of 3

96. Question
1 pointsCategory: Quantitative AptitudeA can do a piece of work in 6 days. B is 50% more efficient than A. In how many days A and B together can complete the work?
Correct
Explanation:
A in 6 days, B 50% more efficient, so ratio of days in which A and B can do work is
A : B = 150/100 : 1 = 3 : 2
So 3x = 6days, x = 2, so B alone can do in 2x days = 4 days
So both can do in = (6*4)/10 = 12/5 daysIncorrect
Explanation:
A in 6 days, B 50% more efficient, so ratio of days in which A and B can do work is
A : B = 150/100 : 1 = 3 : 2
So 3x = 6days, x = 2, so B alone can do in 2x days = 4 days
So both can do in = (6*4)/10 = 12/5 days

1 pointsCategory: Quantitative AptitudeIf the difference between simple interest and compound interest on a certain sum of money for 3 years at 10% per annum is Rs 31, what is the sum?
Correct
Explanation:
When rate is same, difference between SI and CI for 3 yrs = Pr^{2}(r+300)/100^{3}
So 31 = P*10*10*310/100*100*100
Solve, P = 1000Incorrect
Explanation:
When rate is same, difference between SI and CI for 3 yrs = Pr^{2}(r+300)/100^{3}
So 31 = P*10*10*310/100*100*100
Solve, P = 1000

Question 100 of 100
100. Question
1 pointsCategory: Quantitative AptitudeA solid cone of height 10 cm and diameter of base 20 cm is cut out from a solid sphere of radius 10 cm. Find the percentage of wood wasted.
Correct
Explanation:
Volume of sphere = (4/3)ᴨr^{3}
Volume of cone = (1/3)ᴨr^{2}h = (1/3)ᴨr^{3} [since r = h]
Both radius are same and height is also equal to radius, so
Wood wasted = (4/3)ᴨr^{3} – (1/3)ᴨr^{3} = ᴨr^{3}
So % of wood wasted = [ᴨr^{3}]/ [(4/3)ᴨr^{3}] * 100
= (3/4)*100 = 75Incorrect
Explanation:
Volume of sphere = (4/3)ᴨr^{3}
Volume of cone = (1/3)ᴨr^{2}h = (1/3)ᴨr^{3} [since r = h]
Both radius are same and height is also equal to radius, so
Wood wasted = (4/3)ᴨr^{3} – (1/3)ᴨr^{3} = ᴨr^{3}
So % of wood wasted = [ᴨr^{3}]/ [(4/3)ᴨr^{3}] * 100
= (3/4)*100 = 75
