C+7 is divisible by 5 it means c=end with 3 or 8 with unit place.
so we need 7 or 2 in unit place nd no square integer value will end with 2 or 7 in unit place when we square it so plss check the question so if yu write n^2 then it is wrong nd if you write it n*2 then it must be n=6.

c+7 is divisible by 5, also (c+n2) is divisible by 5, if we add and substract 7 in (c+2*n) we get (c+7+2*n-7). where whole equation is divisible by 5 also (c-7) is divisible by 5 so (2*n-7) should be divisible by 5.

Sequence is 1,-2,3,-4,5,-6 . Wat is the sum of first 200 terms of the sequence
Reply Like? Yes (1) | No   
Devendra Marghade   10 years ago
-100

Here sum can be taken of two series 1st 1,3,5,7,......,199 and 2nd -2,-4,-6,-8,......,-200 and each series will contain 100 terms out of total 200
Sum of 1st series=(100/2)[2*1 + (100-1)*2]=50*[2+ (99*2)]=10000
Sum of 2nd series=(100/2)[2*(-2) + (100-1)*-2]=50*(-202)=-10100
So sum of 200 terms=10000-10100=-100

ans-(-59500)...becz at first we find the last term means tn term with the help of formula tn=a+(n-1)d and after that we can use the formula sn=n/2(a+l). here l is basically the tn term which is the last term.so
tn=1+(199)*(-3),so value is -596,and then we use this value in rest formula we can get the exact answer

(1+3+5+..........)-(2+4+6+......).they both are in a.p.
so odd series will have 100 terms and even series will have 99 terms by using the formula tn=a+(n-1)d.so sum of the terms in a.p.,when their ends are known is,sum=n/2(a+l).
so sum=50(200)+99/2(202)=10000-9999=1

Raj drives slowly along the perimeter of a rectangular park at 24kmph & completes 1 full round in 4 mins. If ratio of length to breadth of park is 3:2. Wat are its dimensions
Reply Like? Yes | No   
Devendra Marghade   10 years ago
480 m. & 320 m.

If length=3x and Breadth=2x, then distance along the perimeter of rectangle=2(3x+2x)=10x
With the speed of 24 Kmph, distance covered in 4 min.=4*24/60=8/5 Km.
As here,10x=8/5 Km., so x=8/50 or 4/25 Km.
So dimension of park are length=3x=3*4/25=12/25 Km. or 12*1000/25=480 m. and
breadth=2x=2*4/25=8/25 Km. or 8*1000/25=320 m.

36) What are the last two digits of expression 5306^214 ?
Reply Like? Yes | No (1)  
Onlinepsa.in   10 years ago
5306^214 = (5300+ 6)^214
If you work out the binomial expansion every term will have atleast 2 zeroes in the end except 6^214.

Last two digits of (5300+ 6)^214= Last two digits of 6^214

6^214 = 2^214 * 3^214

2^214 = 2^(10*21+4)
= (1024)^21 * 2^4
= (24)^21 * 2^4
=24^odd * 2^4
=24* 16 [ 24 to the odd power is always 24 and even power is always 76]
=84

3^214 = 3^(4*53+2)
= (81)^53 * 09
= 41 * 9
=69

Last two digits of 6^214 = 84*69= 96
-----------------

Alternatively, you can observe the pattern of 6^n [ where n=1,2,3,4 and so on]

The last two digits of the pattern 06, 36, 16, 96, 76, 56, 36, 16, 96, 76, 56 ....
[Only first power gives 06, all others are repetitive after every 5 numbers. If you could remove first power, you would see a

repeatition of numbers].

First thing to do is to subtract one from 214 power. Now, we need to get the remainder when we divide 213 by 5. Remainder is 3.
Thus, last two digits will be 3rd in the repeating pattern ie. 96.

As we know the formula for
speed of upstream = (u-v)
speed of downstream = (u+v)

Solution :-
Speed of upstream = (5-3) = 2 km/hr
Speed of downstream = (5+3) = 8km/hr

As they asked about time of travel:-
total distance / speed of upstream = 24km / 2km/hr = 12hrs
total distance / speed of downstream = 24km / 8km/hr = 3hrs

answer is 11/120,
method : product of two numbers = HCFxLCM, so given x+y=55=>x and 55-x are two numbers
x(55-x)=120x5 => x^2-55x+600=0 so after solving u get x=40 and y=15 or x=15 and y=40 either way u get the reciprocal sum as 11/120

60

With A,B combinations C or D or E are possible, with A,C combinations B or D or E are possible, with A,D combinations B or C or E are possible, with A,E combinations B or C or D are possible
So total 12 combinations for A are possible for selecting 3 among 5 like (A,B,C), (A,B,D), (A,B,E), (A,C,B), (A,C,D), (A,C,E), (A,D,B), (A,D,C), (A,D,E), (A,E,B), (A,E,C), (A,E,D)
Similar 12 combinations are possible for remaining 4

Then, which is always true for T.

consider tr (3,4,5)
then T = (3+102)^2 + (4+102)^2 + (5+102)^2
= (3^2+4^2+5^2)+ 3*102^2 + 2*102*(3+4+5)

In the triangle P1 Q1 R1, the points P2, Q2 and R2 divide the sides P1Q1, Q1R1 and P1R1 in the ratio 3 : 2 each. A new triangle is constructed by joining the points on the sides of triangle P2Q2R2 that divide these sides in the ratio 3 : 2. This process of forming triangles continues infinitely. Find the ratio of the area of triangle P1Q1R1 to the sum of the areas of all the formed/constructed triangles (P2Q2R2, P3Q3R3…) whose areas are smaller than the area of the triangle P1Q1R1.
