One lady has 2 children, one of her child is boy, what is the probability of having both are boys

A1/2

B1/3

C1/4

D1/5

ENone of above

| | Important Formulas | Topic: | Asked In |

Explanation:

In a family with 2 children there are four possibilities:
1) the first child is a boy and the second child is a boy (bb)
2) the first child is a boy and the second child is a girl (bg)
3) the first child is a girl and the second child is a boy (gb)
4) the first child is a girl and the second child is a girl (gg)
Since we are given that at least one child is a girl there are three possibilities: bg, gb, or gg. Out of those three possibilities the only one with two girls is gg. Hence the probability is 1/3.

P=(b,b)(b,g)(g,b) = 1/3 for both boy

Choose the correct option.

5% of income of A is equal to 15% of income of B and 10% of income of B is eqaul to 20% of income of C. If income of C is Rs. 2000, then total income of A, B and C is

ARs. 6000

BRs. 18000

CRs. 20000

DRs. 14000

| | Important Formulas | Topic: | Asked In |

Explanation:

let x be the income of 'B'and'c'
Now,income of B is=(10/100)*x=(20/100)*2000(since 10% of income B is equal to 20% of income c)
Therefore, solving,x=4000 i.e)B=Rs.4000
Likewise income of A is=(5/100)*x=(15/100)*4000(since 5% of income A is equal to 15% of income B)
Therefore,A=Rs.12000
Total of A,B and C is=2000+4000+12000=18000 Rs.

3 machines a,b,c can be used to produce a product. Machine a will take 60 hours to produce a million units. Machine b is twice as fast as machine a. Machine c takes the same amount of time as machine a and b taken together. How much time will be required to produce a million units if all the three machines are used simultaneously?

A12 hours

B10 hours

C8 hours

D5 hours

ENone of above

| | Important Formulas | Topic: | Asked In |

Explanation:

1 hour capacity of
Machine a =1/60 million
Machine b =2*(1/60)=1/30 million
Machine c =(1/60)+(1/30)=1/20 million
So in 1 hour Machines a,b & c will produce (1/60)+(1/30)+(1/20)=1/10 million
Time taken to produce 1 million units=1/(1/10)=10 hours

and the White balls = 3 *2 = 6
i.e., White = 6 ; Black = 12 ; Grey = 9 (Since 2:4:3 ratio)

A3 days

B4 days

C5 days

D6 days

| | Important Formulas | Topic: | Asked In |

Explanation:

Therefore for 10 days= 10 *24hours= 240hours of work done by 12men.
8 men working for 6hours in a day means= 8 *6hours= 48hours of work is completed in 1 day.
Therefore,
= 240/48=5days take to work by 8 men for 6hours in a day.
