20946.The cost price of a television is Rs 2400 which is 20% below the market price. If it is sold at a discount of 16% on the market price then find its market price, selling price and profit?
Rs 3000, Rs 2520, 5%
Rs 4000, Rs 3520, 6%
Rs 5000, Rs 6250, 7%
None of the above
Explanation:

Let, M.P of the television = x.

According to the question, C.P. = x - 20x/100

=> 2400 = (100x-20x)/100

=> 2400 $\times$ 100 = 80x

$\therefore$ Market Price i.e. x = (2400 $\times$ 100)/80 = Rs. 3000

Now S.P = MP - Discount

= 3000 - 480. (because discount in rs = (16/ 100) $\times$ 3000 = 480)

= 2520.

profit = 2520 - 2400 = 120 i.e. 5%

20947.The average age of five girls 11. The oldest among them is 15 years old. What is the average of the others?
20
15
10
none of these
Explanation:

Let `T` be the total age of 5 girls.

Then, T/5 = 11.

=> T = 55.

Given, Age of the Oldest girl = 15.

Then, Total age of other 4 girls will be 55-15=40.

So, Avg. of other 4 girls 40/4 = 10.

20948.What must be added to the two numbers, which are in ratio 5: 12, so that the new ratio becomes 3:4?
5
8
12
16
Explanation:

Let x be the required number.

Then, According to the question,

=> (5+x)/(12+x) = 3/4

=> 20 + 4x = 36 + 3x.

=> x = 16.

20949.Today, the age of a father is thrice the age of his son. After 5 years the age of father will be 2.5 times the age of his son. What is the age of son today?
20 years
15 years
1 years
22 years
Explanation:

Let the age of son = S years and the age of father = F years.

According to the question,

=> F = 3 $\times$ S.

=> F = 3S.

After 5 years,

=> (F+5) = 2.5 $\times$ (S+5).

=> 3S + 5 = 2.5S + 12.5 [put F=3S]

=> 0.5S = 7.5

=> S = 15

Hence, the age of son = 15 years.

20950.In a school the ratio of boys and girls are in the ration 5:6. 25% of boys will get scholar ship and 20% of girls will get scholar ship what % of students wont get scholarship?
71%
70%
78%
none of these
Explanation:

According to the question,

Boys: Girls => 5x: 6x

Total no. of students including boys and girls = 5x + 6x = 11x

25% of boys => 5x $\times$ 25/100 = 5x/4

20% of girls => 6x $\times$ 20/100 =6x/5

No. of students who are getting scholarship => 5x/4 + 6x/5 = 49x/20

No. of students who are not getting scholarship = 11x - 49x/20 = 171x/20

Hence, the percentage of students not getting scholarship => 171x/20/11x $\times$ 100

=> 100 $\times$ 171x/220x.

=> 77.7% = 78%(approx.).

20951.A and B can together finish a work in 30 days. They worked at it for 20 days and then B let. The remaining work was done by A alone in 20 more days. B alone can do the entire work inoption
48 days
50 days
54 days
60 days
Explanation:

According to the question,

A+B`s 1-day work = 1/30.

A+B`s 20 days work = 20 $\times$ 1/30 = 2/3.

Remaining work left = 1-2/3 = 1/3.

A does 1/3 work in ---> 20 days.

A does 1 work in ---> x days.

=> x = 3 $\times$ 20 = 60 days.

A will take 60 days to complete the whole work.

So, A`s 1-day work = 1/60.

Therefore, B`s 1-day work = (A+B)`s 1-day work - A`s 1-day work.

=> 1/30 - 1/60 = 1/60

So, B`s 1-day work = 1/60

Hence, B will complete the entire work alone in 60 days.

20952.A sum of money at simple interest amounts to Rs. 2240 in 2 years and to Rs. 2600 in 5 years. What is the principal amount?
1000
1500
2000
2500
Explanation:

SI for 3 years = 2600-2240 = 360

SI for 2 year 360/3 $\times$ 2 = 240

principal = 2240 - 240 = 2000.

20953.If a man rows at the rate of 6 kmph in still water and his rate against the current is 4.5 kmph, then the man`s rate along the current is:
6 kmph
7.5 kmph
6.5kmph
8 kmph
Explanation:

Let the rate along the current be x kmph.

Then, (x + 4.5)/2 = 6.

$\therefore$ x = 7.5.

20954.Rs.900 is divided among Maya, Annie, Saiji so that Maya receives half as much as Annie and Annie half as much as Saiji. Then Saiji`s share is:
Rs.200
Rs.300
Rs.400
Rs.600
Explanation:

Let Saiji`s share is x.

Then, Annie`s share = x/2 and Maya`s share = x/4.

Therefore, Maya: Annie: Saiji = x/4: x/2: x = 1: 2: 4.

Therefore, Saiji`s share = Rs. 900 $\times$ 4/9 = Rs.400.

20955.A rectangular carpet has an area of 60 sq.m. If its diagonal and longer side together equal 5 times the shorter side, the length of the carpet is:
5m
12m
13m
14.5m
Explanation:

Let, length= x meters and breadth= y meters

Then xy=60 and $(x^2+y^2) $+ x= 5

Therefore, x=60 and $(x^2 + y^2)$ = $(5y-x) ^2$.

Or xy=60 and $24y^2$-10xy = 0.

Therefore, $24y^2$ - 10 $\times$ 60 = 0 or

=> $y^2$ = 25

=> y = 5.

Therefore, x= (60/5) m= 12m.

So, length of the carpet = 12m

20959.Coding-Decoding:

If COMPLETED is coded as MOCELPDET, then DIRECTION will be coded as:

RIDTCENOJ
SIDTCENOI
RIDTCENOI
RIETCENOI
Explanation:

In given word, word is divided into three parts like

COM+PLE+TED, then these parts are written in reverse order as MOC+ELP+DET

So DIRECTION will be DIR+ECT+ION, which will be RIDTCENOI.

20960.Coding-Decoding:

In a certain code language COMPUTER is written as RFUVQNPC. How will MEDICINE be written in that code language?

MFEDJJOE
EOJDEJFM
MFEJDJOE
EOJDJEFM
Explanation:

There are 8 letters in the word.

The coded word can be obtained by taking the immediately following letters of word, expect the first and the last letters of the given word but in the reverse order. That means, in the coded form the first and the last letters have been interchanged while the remaining letters are coded by taking their immediate next letters in the reverse order.

Data-Sufficiency:

How many students are enrolled in Sastri`s Quant class?

(I). If 3 more students sign up for the class and no one drops out, more than 35 students will have enrolled in the class.

(II). If 4 students drop out of the class and no more sign-up, fewer than 30 students will have enrolled in the class.

Solution:

Statement I alone is not sufficient, but I does imply that at least 33 students are enrolled in the class. Statement II alone is not sufficient, but II does imply that no more than 33 students are enrolled in the class.

Although neither statement alone is sufficient, the two statements taken together are sufficient to answer the question that the number of students enrolled in the class is 33.

20962.Data-Sufficiency:

Question: Who among P, Q, R, S and T is the lightest?

(I) R is heavier than Q and T but lighter than S.

(II) S is not the heaviest.

I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Neither I nor II is sufficient
Explanation:

From I, we have: R>Q, R>T, S>R i.e. S>R>Q>T or S>R>T>Q.

From II, S is not the heaviest. So, P is the heaviest.

Thus, we have: P > S > R > Q > T or P > S > R > T > Q.

Hence, either T or Q is the lightest.
