15x+10y=380

y=8

x=20

ho gya satisfy...

Its 1180. check again bro

1

what about x,y,z..are they real no's or integers?

Reminder is 3..

Substitute the values...when z=7,15(20)+10(+7(7)=429

Substitute the values...when z=7,15(20)+10(+7(7)=429

z=7 , x=20, y=8

remainder = 3

2011 = 6K + 1 ;(E (7)= 6)

2011 = 6K + 1 ;(E (7)= 6)

3 it should be.

Euler (7) = 6

3^6K = 1 Mod(7)

3^2010 = 1 Mod(7)

The remainder is 3

3^6K = 1 Mod(7)

3^2010 = 1 Mod(7)

The remainder is 3

15x + 10y + 7z = 429

What is the minimum value z can have?

a)7

b)12

c)17

d)22

What is the minimum value z can have?

a)7

b)12

c)17

d)22

varun bhai plz ise explain kar do samajh ni aaya ye

is it 1080rs..with 1 guava of cost 80...

1

For no green balls = 1 way

For 1 green ball = 6 ways

For 2 green balls = 4+3+2+1 = 10 ways

For 3 green balls = 4 ways

Total = 21 ways

Q- 3 mangoes, 4 guavas and 5 watermelons cost rs 750. 10 watermelons, 6 mangoes and 9 guavas cost 1580. what is the cost of 6 mangoes, 10 watermelons and 4 guavas ?

say q=6

=> pq = 16, pr = 10, qp = 61, pp = 11

pqr = pq*pr = 16*10 = 160

prrp = 1001

(qp prrp)/pp = 61*1001/11 = 0 remainder

i use to have have problems in identical ball and box concept in combinatories/permutation

how to tackle those problems

the discussed question related to filling of boxes from 1 to 6 so that no two adjacent boxes contain green coloured box for case iii)when there are two ball...

so sum to 2 terms is 3/2 ...

now using options.... (pq+1)/2 satisfies

Option 3 it would be.

a+b+c+d+.....upto r terms = n

is given by C(n+r-1,r-1)...In this case n = 12 and r = 3

C(14,2) = 91

@Koshti bhai: Welcome back bhai!!!! How was your CAT ??
