- Study the following and answer the questions:

What is the two digit number?

a)The sum of two digit number is 6.

b)The difference two digit number is 0.Only a is sufficientOnly b is sufficientEither a or b is sufficientNeither a nor b is sufficientBoth a and b is sufficientOption E

p+q=6

p-q=0 then p=3,q=3

Solve both the equations. - How many males and females can complete a piece of work in 15 days?

a)If 12 male can complete the same work in 20 days.

b)If 10 female and 6 male complete the same work in 12 days.Only a is sufficientOnly b is sufficientEither a or b is sufficientNeither a nor b is sufficientBoth a and b is sufficientOption E

12M=1/20

1M=1/12*20

10F+6M=1/12 - What is the profit earned by selling a mobile phone for Rs 17525?

a)The Cost Price of 5 such mobile phones is equal to the Selling Price of 4 such mobile phones.

b)13% profit is earned by selling each mobile phone.Only a is sufficientOnly b is sufficientEither a or b is sufficientNeither a nor b is sufficientBoth a and b is sufficientOption C

From a:CP=4/5=100*17525/125

From b:113*17525/100 - How many techers are there in the class?

a)The average weight of class is 46 kg.

b)If 2 teachers weighing 38 kg and 32 kg leave the class and are replaced by 48 kg and 40 kg then the average weight is increased by 2.5 kg.Only a is sufficientOnly b is sufficientEither a or b is sufficientNeither a nor b is sufficientBoth a and b is sufficientOption B

Total-46*x

New Total=48.5*x

48.5x-46*x=48+40-38-3236 - What is the salary of Xylo in a group of Xylo,Yash and Zakira whose average salary is Rs 36,700?

a)Total salaries of Yash and Zakira is Rs 78,650.

b)Total salaries of Xylo and Yash is Rs 97,550.

Only a is sufficientOnly b is sufficientEither a or b is sufficientNeither a nor b is sufficientBoth a and b is sufficientOption A

Total salary=36700*3=110100=Xylo+Yash+Zakira - A cup was sold for Rs 336,if the perentage of profit is equal to Cost Price ,then find Cost Price?
Rs 155Rs 140Rs 150Rs 200Rs 215Option B

(100+x)% of X=Rs 336

100x+x^2=33600

x^2+100x-33600=0

Solve the equations,we get x=140 - Ramesh gains 15% by selling a tV for a certain price.If he sells it at double the price,then the percentage of profit will be which of the following?
125%135%130%145%None of theseOption C

CP=Rs 100 ; Gain=15%=Rs 115

SP=Rs 230

Then Profit=Rs 130

%Profit=130% - Priyank bought two Tvs which together cost him Rs 440.He sold one of the TVs at a loss of 20% and the other one at gain of 40%.The selling price of both TVs are same.Then find out the cost price of both TVs?
Rs 160 and Rs 280Rs 120 and Rs 250Rs 100 and Rs 220Rs 180 and Rs 310None of theseOption A

80/100*x=140/100*y

x=7/4y

x+y=440

7/4y+y=440

y=160;x=280 - What is differnece between the CI and SI on Rs 6500 at rate of 4% per annum in 2 years?

- Find the Compound Intrest on Rs 4500 at 4% per annum for 2 years compounded half yearly?
Rs 639Rs 750Rs 780Rs 739None of theseOption A

CI=P{1+(R/100)^n-1
