A retailer keeps Reebok shoes, which are listed at a mark up of 10% above their factory price. However on Monday he realized the shortage of demand and hence decreased the list price by 10%. On the very next day, that is, Tuesday he realized that he is making a loss so he increased yhe list price by 10% again. He continues this trend indefinitely. On which day will he suffer a loss of more than 10% per shoe for the first time?

13/2 minutes = 7/3 metric ton

so 1 hour = 7x2x60/13x3 =280/13 metric ton

let it fill 70 in x hrs so

(280/13-15)*x=70

x=14*13/17

so speed = 156/x

x=14.42 = 14.5

so 1 hour = 7x2x60/13x3 =280/13 metric ton

let it fill 70 in x hrs so

(280/13-15)*x=70

x=14*13/17

so speed = 156/x

x=14.42 = 14.5

let d be distance btw PQ

speed of vikrant = d/6

viraat = d/9

in 1 hour vikrant moves = d/6

distance left = 5d/6

time at which they meet after 1 hour = (5d/6)/(d/6 + d/9) = 3

hence total = 1+3 = 4

speed of vikrant = d/6

viraat = d/9

in 1 hour vikrant moves = d/6

distance left = 5d/6

time at which they meet after 1 hour = (5d/6)/(d/6 + d/9) = 3

hence total = 1+3 = 4

The sum of the lengths of the hypotenuse and one of the perpendicular sides of a right angled triangle is L. When the area of this triangle is maximum, the angle between the two sides is

Please provide the approach as well

1) 45 degrees

2) 22.5 degrees

3) 60 degrees

4) None of these Skip

—

let the three sides of the triangle be P,B and H.

p^2+B^2=H^2........eq1

A/Q P+H=L

so, H=L-P

substitute H in eq1

p=(L^2-B^2)/2L

area= 1/2*B*P

for Area to be max derivative will be 0.

which gives L^2=3*(B^2)

so, B = L/sqrt(3)

p=L/3

sin X=1/2

X=30 deg

hence ANS 4 None of these

Two Rabbits A and B are running a race in which they have to go upto 50 m mark and then come back to starting point. A runs in a sequence of 3 steps in which distance traveled in first jump is twice that of other two and B runs in a sequence of 3 jumps where first jump is 1.5 time the distance travelled in second jump and distance traveled in 2nd jump is twice the distance traveled in 3rd jump. Distance traveled by A in 2 jumps and by B in 3 jumps is equal to 6m. Who will win the race.

Please explain the approach!

all even nos and powers will be divisible by 4....like 2^2 4^4 and so on....bache all odd nos and theirs powers like 1^1 3^3 5^5 will give remainders in form of +1 -1 +1 -1 and so on....since we have even no of nos all get cancelled leaving us with remainder 0

Just break it down in 4 consecutive terms in a block. So the nth block is (4n+1)^(4n+1)+(4n+2)^(4n+2)+(4n+3)^(4n+3)+(4n+4)^(4n+4). So the the sequence given is the sum of 25 blocks from n=0 to n=24. Now (4n+1)^(4n+1)= sum all multiples of 4 +1^(4n+1) {By binomial theorem}. The remainder when divided by 4 is 1. The second term (4n+2)^(4n+2) is clearly divisible by 4 {take 2 common out from and the term becomes a multiple of 4} and hence remainder is 0. The same happens for the last term (4n+4)^(4n+4). The third term we can write as (4n+4-1)^(4n+3)=(4m-1)^(4n+3) [m=n+1]. Now again (4m-1)^(4n+3)= sum of multiples of 4 +(-1)^(4n+3). When divided by 4 the remainder is (-1)^(4n+3)=(-1)^3=-1. So the sum of the remainder from four terms is 1+0+(-1)+0=0 and when summed fro all 25 blocks the final remainder is also 0.

the average speed of a train in the onward journey is 25% more than that in the return journey. The train halts for one hour on reaching the destination. The total time taken for the complete to and fro journey is 17 hours, covering a distance of 800km.speed of the train in onward journey is:

A 45kmph

B 47.5kmph

C 52kmph

D 56.25kmph

Hi,

Could anyone share some insight on the approach to solve this problem

Q> Which of the following is smallest?

a) 5^(1/2) b)6^(1/3) c)8^(1/4) d)12^(1/5)

Q> Which of the following is smallest?

a) 5^(1/2) b)6^(1/3) c)8^(1/4) d)12^(1/5)

- 12^1/5. 04 Mar.
- LCM(2,3,4,5)= 60 5^(1/2)= (5^30)^(1/60) 6^(1/3)= (.... 28 Aug '13.

LCM(2,3,4,5)= 60

5^(1/2)= (5^30)^(1/60)

6^(1/3)= (6^20)^(1/60)

8^(1/4)= (8^15)^(1/60)

12^(1/5)=(12^12)^(1/60)

Now since the power over all the numbers is (1/60), the ans will be smallest of all the numbers, i.e (12^12) in this case.
