.33 of a number is .002 ofanother. What is the ratio of

these numbers? Let us assume that the number is 66. Now letus get the first number by dividing 6 by .333.

We get: 66/.33 = 200. let us now get the 2nd

number by dividing 66 by .002. 66/.002 = 33000. thus ratio of the numbers is

: 1:165 answer.

A,B, C start a business withcapital in ratio of 1/3 , 1/5

and . A withdraws half ofhis capital after 6 months.

But B doubles his capitalafter 6 months. Annualprofits are Rs. 10000. how

do you divide the profits?

Let us take LCM of 3,5,4 = 60. Now multiply 60 by

these ratios: 20, 12, 15.

A will withdraw half after 6 months, so his capital is10*6 +20*6 = 180. 12*6 + 24*6= 216. , 15*12 = 180.

thus new ratio of their capital is : 180:216:180. their

ratio is :10:12:10 or 5:6:5. thus their profits are :

5/16*10000 =3125,3750 and 3125 ans.

What is value of (14+7)^4?

21^4 =194481 answer. Or

(20+1)^4 =

A^4+4A^3B+6A^2b^2+4ab^3+b^4

=160000+32000+2400+80+1

=194481 answer.

99^4?

(100-1)^4

We know that (a-b)^4 = a^4-4a^3b+6a^2b^2-

4ab^3+b^4

100000000-4000000+60000-400+1

=96059601 answer.

2. Pipe X can fill the tank in 10 minutes

3. Pipe Y can empty the tank in 6 minutes.

DATA SUFFICIENCY QUESTION?

What is the time taken by 2 pipes to empty or fill

a tank that is 2/3 full?

2. Pipe X can fill the tank in 10 minutes

3. Pipe Y can empty the tank in 6 minutes.Answer: with the help of both the statements, we

can find when will the tank be emptied.

1/6 1/10 = 4/60 OR 1/15. We can empty filled tank

in 15 minutes. But the tank is 2/3 filled, so time

will also be 2/3 thus 15*2/3 = 10 minutes.

DATA SUFFICIENCYQUESTION: Is X ^2 an integer?

2. 3x^2 is an integer

From second statement, it is not clear whetherX is integer or not- because a fraction canalso be negative.
