2.
Five farmers have 7,9,11,13 & 14 apple trees respectively in their orchards.last year each of them discovered that every tree in their own orchard bore exactly d same no of apples.further,if d 3rd farmer gives one apple to the 1st,& the 5th gives 3 to each of the 2nd & d 4th,they would all exactly have the same no of apples, what were d yields per tree in the orchards of d 3rd & 4th farmers?

ANS:
11,9

Let the number of apples in each tree of the 5 farmers be a, b, c, d,e respectively. Therefore total no of apples are 7a, 9b, 11c, 13d and 14e respectively.

Given,
7a+1 = 9b+3 = 11c-1 = 13d+3 = 14e-6 = x

9b+3 = 13d+3
===> 9b = 13d
so take b = 13 and d = 9

9b+3 = 9*13+3 = 120
ie, x=120

substituting
7a+1 = 120
7a = 119
a = 17

11c-1 = 120
11c = 121
c=11

14e-6 = 120
14e = 126
e = 9

Yields per tree in the orchards of d 3rd & 4th farmers= 11,9

(b) ll be the answer

5. It_____ have been my show.
a)should
b)would
c)could
d)not
ANS”:  (c) could have been my show
6. Solve
(x-a)*(x-b)*(x-c)*...........(x-z)=?
ANS”:
(x-a)*(x-b)*(x-c)*...........(x-z)
= (x-a)*(x-b)*(x-c)*...........(x-x)*(x-y)*(x-z)

since (x-x)=0 so, whole product is zero

(x-a)*(x-b)*(x-c)*...........(x-z )= 0
7. 2^81 when divided by 6,what is the remainder
ANS:
 2^81/6 ====> (2^1*2^2*2^3*....81 times]/6

2^1/6 ----------> remainder=2
2^2/6 -->4/6 ---> remainder=4
2^3/6 -->8/6 ---> remainder=2
2^4/6 -->16/6 --->remainder=4
2^5/6 -->32/6 --->remainder=2
.
.
.
it goes on in a cyclic manner

so remainder is "2" for all odd powers of 2 nd "4" for all even powers of 2

here 2^81 which has the odd power

so remainder =2

12. find the odd one
cde
pqr
tuv
mno
ANS: Sequence is maintained in all the four options. The only point through which one can be called odd is the presence of a vowel in it.
cde-vowel 'e'
pqr-no vowel
tuv-vowel 'u'
mno-vowel 'o'
So, the odd one is pqr

13.
find the odd one
adg
hkn
psw
mps
ANS: psw

since difference between each characters in every word is 3, but psw doesnt follow this

adg - 147 ==>( 4-1=3, 7-4=3)
hkn - 8,11,14 ==> (11-8=3, 14-11=3 )
mps - 13,16, 19 ( 16-13 =3 , 19-16= 3)
psw - 16, 19, 23 ==> (19-16=3 , 23-19= 4)

Hence ans : psw

14.
find the odd one
adp
qtx
hkr
ste
ANS: I guess its ste

adp -- 1,4,16 {1+4+16= 21}
qtx -- 17,20,24 {17+20+24= 61}
hkr -- 8,11,18 {8+11+18=37}
ste -- 19,20,5 {19+20+5 = 44}

except "ste" ,other words produce even results

So ans : ste


15. Diamonds value is proportional to its weight. when diamonds broke into pieces in ratio 1:2:3:4:5 total loss in value is 85000. what is the value of the diamond twice the weight of original diamond.

ANS ;
There will be no loss.

2 (x+2x+3x+4x+5x)=85000 =>x=8500/3
Now it said that value of the diamond is twice the Weight of original diamond therefore,
Value = 2 (x)+2 (2x)+2 (3x)+2 (4x)+2 (5x) = 30x
Then, 30*(8500/3) = 85000.
Therefore their is no loss.
value= (weight)^2
But if you take value of diamond is square of its weight then we will have loss of 74000.

16. Diamond\s value is proportional to its weight 2 .When the diamond broke what of pieces in ratio 1:2:3;4:5. Total loss in value is 85,000. What is the value of the diamond twice the wt of the original diamond.


ANS:
let weight of the original diamond be 15k ( This number is the sum of the numbers in the ratio given ) ,so, it's value would be 225k^2. Now, the broken diamond's value adds upto 55k^2(. So, loss of value is 170k^2 which is 85,000.  [85,000/170]   This gives k^2 = 500.

We need (30k)^2 = 900k^2 = 900* 500 = 450,000
from where this 55k^2 come??

add the square of ratios u will get 55k^2...1+4+9+16+25=55

17. emblem is coded as 216;
