Choose the correct option.

A' and 'B' complete a work togather in 8 days.If 'A' alone can do it in 12 days.Then how many day 'B' will take to complete the work?

A25 days

B24 days

C20 days

DNone of these

| | Important Formulas | Topic: | Asked In 5 |

Explanation:

A & B one day work = 1/8
A alone one day work = 1/12
B alone one day work = (1/8 - 1/12) = ( 3/24 - 2/24)
=> B one day work = 1/24
so B can complete the work in 24 days.

A = 12, A+B = 8, B = ?

Take LCM of A & A+B = 24.

So, A=12*2 = 24, A+B = 8*3 = 24, B = 1*24 = 24.

A8400

B1800

C273000

D227000

| | Important Formulas | Topic: | Asked In |

Explanation:

Total no. of ways ENGINEERING can be arranged is
E=3, N=3, G=2, I=2, R=1
=11!/(3!*3!*2!*2!) => 277200

No. of ways vowels come together
Vowels ==> (eieei)ngnrng =>
EIEEI an be considered as 1 letter ... so 1!
NGNRNG = 6!
EIEEI can be arranged as 5!/(3!*2!)
NGNRNG can be arranged as 6!/(3!*2!)

So (1!+6 !)*5!/(3!*2!*3!*2!) = 4200
So no. of ways vowels not come together = 277200 - 4200 = 273000
Ans : 273000
