ii. The female sitting between N and P is not Q.

iii. Q sits 4th to the right of R.

iv. R’s spouse is N.

v. U sits exactly between S and O and they face in opposite directions.

vi. S is a male sitting with two females and one of them has husband facing towards the centre who is sitting 3rd to the left of N.

vii. The person sitting 2nd to the left T is the wife of T and they face in same direction.

7/10 ty az

6 to 10 kiye kya tell me

Hardly 2 correct aaya 6 the&10 the que

vhi btaao

6th mai

B+D=13/200

After 8 min means =13/25 work in 8 min me b&d work karenge

So remaining work 200/13-8=96/13 left

R open hone ke bad additional work bd&r milke

b+d-r=96/13+128/39=32/3 min

Total work lelo

B+D-R

13/25+(13/200-1/R)32/3=1

X=50

ye to solution me hi diya hai

Ha kya samja to batao

anyone done 8th question

I am gtting x=28/3………but in sol it is given x=6 ????

Nice mam plz aese questions post kiya kro

anyone getting 8th question ??

x=6 comes only ..

solve the equation once again plz.. u will get 6 as value .

Ha question m printing mistake h 1/40 filled dia h bt solve krte time 11/40 liya h

And isko 11/40 suppose krke kre to

Tw 240

11/40 alrdy filled so remaining

240*29/40=174

C=5

D=6

P=-4

In 6 min c+d=6*11=66

Remain=174-66=108

Now

2t(5+6)-t4=108

18t=108

T=6

C wrk fr 18 min

C=18*5/240=3/8

bm band ho gya na ab ?

Ha yr

A boy has 3 library tickets and 8 books of his interest in the library of these 8, he does not want to borrow maths part 2 unless maths part 1 is borrowed? In how many ways can he choose the three books to be borrowed??

2t(5+6)-t4=108

??

c =48

d=40

p =-60

lcm =240 =>c =5 ,d =6 p =-4

now 11/40 part =11/40*240 =66

now let p is opened after x min frm c and d now given condition is that opening tym of p = to closing tym

=> 66 +11x +(11-4)x +6*11 =240

=>132 +18x =240 =>18x =108 =>x =6min

now this is the closing tym => until this time c and both works 2x (x before p +x with p) time =>totl time taken by c =totl tym taken by d =2x+6 =2*6+6 =18min

=> fraction filling of tank by c =18/48 =3/8

1/40th part diya hai Q me 11/40 kaise?

11/40 dia h bhai dekiyee aap 11/40 part of tank is filled dia h naaa…:)))

bro…yha pey to 11/40 diya hua hhhh …:)))

after f5 aa gya …:))

A boy has 3 library tickets and 8 books of his interest in the library of these 8, he does not want to borrow maths part 2 unless maths part 1 is borrowed? In how many ways can he choose the three books to be borrowed?.

total ways for selection of 3 books from 8 => 8c3 =56

now total toltl no ways for selecting book other than maths book both part =6c2 =15

so totl ways of selecting 3 books=56-15 =41

isme vo ek part 2 k place pr part1 prefer krta h …to apne dono part kyu nikale h 6c2 ????

nhi wo tbi maths k pehle part ko lega jb dusra b available ho to h jaise probablity nikalte h naa none ki like p(none) =1-p(all) same concept use kia yha pey mam…:)

Thanku soooo much sir…got it now :))))

ji mam shukriyaaa…aapka…:)

Two persons Raj and Ramu started working for a company in similar jobs on January 1, 1991. Raj’s initial monthly salary was Rs 400, which increases by Rs 40 after every year. Ramu’s initial monthly salary was Rs 500 which increases by Rs 20 after every six months. If these arrangements continue till December 31, 200. Find the total salary they received during that period.

ans 152400

raj’s salary increment

=> 400 +440+————————-+upto 10 terms

now sum to n terms of an ap is given by

s(n) =n/2(2a+(n-1)d)

=> r(s) =10/2(800+9*40) =5800

=> totl anuual salary incremnt =12*5800 =69600rs

now ramu’s salary increment

=>500+520+————————+upto 20 terms(1 year =2 half months so 10year = 20 half months)

=>ra(s)=20/2(1000+19*20) =13800

=> totl monthly salary inc.=6*13800 =82800

=> totl money recieved =69600+82800 =152400rs

bro apne 12 & 6 se multiply kyu kiya baad me

sum to nikal diya h na …increment kyu kiya h ???

1st 1 ko 12 se multiply isly kia becoz uski monthly salary h dusre ko 6 se multiply isly kia kyuki uski increment monthly h

🙂 ji shukriya sir apka…howz yr prep going on :))
