@ all

if 2
Upper limit of x+y = 3.99 + 2.99 = 6.98 (almost 7)
Lower limit of x-y = 3.99 - 2.99 = 1

Thus, ratio is 7, option (b)
the answer of ths question given in arun sharma is 4........that is b.\


and in the other question where u hav to find out cost of pencil the answer given is not 14 it is 13..

pls solve ths
1.a numberxy is multiplied by another number ab an dthe result comes pqr where r=2y,q=2(x+y),p=2x where x,y a.11 b.13 c.31 d.22 e.none of ths



2.if the sum of the numbers (a25)^2 and a^3 is divisible by 9 ,then which of the following may b value of a

a.1 B.7 C.9 D.8

4 men and 3 women finish a job in 6 days, and 5 men and 7 women can do the same job in 4 days.how long will 1 man and 1 women take to do the job?
options- (a) 22(2/7) (b) 25(1/2) (c) 5(1/7) (d) 12(7/22)
the ans is (a)

a.1 B.7 C.9 D.8


1. d:22

(10x+y)*(10a+b) = (100p +10q + r) = (200x + 20(x+y) +2y) = (220x+22y)=22(10x+y)

10a+b=22=ab

2.a:1


(a25)^2----> a+2+5
a^3----> a

sum of a+2+5 +a must be divisible by 9
i.e 2a + 7

hence a =1

There are plenty of wrong answers in Arun Sharma. I may be wrong with the 1st question but don't think I can be wrong with the 2nd. Anyway, if you find a fault with the logic, you can let me know but I don't think you would find any, atleast not in the 2nd one.

Hey is the answer 19. Here's how i got it
(90+Bag)/12 is the salary per month. So total salary at 9 months is *9 =65+turban.
270+3b=260+4t
3b+10=4t
Find the choice that satisfies the equation. Then find the salary per month in both cases. It should be equal.
(19+65)/9=

Hi
I have a question
The weight of three heaps of gold are in ratio 5:6:7. By what fractions of themselves must the first two be increased so that ratio of their weights may changed to 7:6:5 ?
(a) 24/25, 2/5
(b) 48/50, 4/5
(c) 48/50, 3/5
(d) 24/25, 3/7

2326

Consider them to be 5 gm, 6 gm and 7 gm respect.
new weights 5+x, 6+y, 7
Now (6+y)/7=6/5

solving, ans is a

It is satisfied for t=10 also.
we will get b=10,
and (10+65)/9=

and for t=55 also.
i have not got the ans yet
2328

Let intially they are 5x,6x and 7x
total intially=18x
later on they will be 7y,6y,5y
total later = 18y

As third heap remain unchanged,
7x=5y=>y=(7/5)x

so first heap=49/5x
second heap=42/5x

so fraction of increase of first heap=24/25
so fraction of increase of first heap=12/30=2/5

hi all,i have problem solving this ques....
The following is known abt 3 real nos x,y,z.
-4a. -16

2330
hi all,i have problem solving this ques....
The following is known abt 3 real nos x,y,z.
-4a. -16

ans a

think

x*z will max at : -4 *-8 = 32
x*z/y , so y suld be min i.e y=2
hence 32/2=16

siml.

x*z is max range covered 4 * -8 = -32
again x*z/y @y=2 hence M=-16

hence range sud be

-16

@bamaratnakaran Instead of asking for the download link, u could ask some puy to give it to u, bcoz thr are lots of ppl who would have no use of this book after joining business school this yr. And esp since ur location is displayed as bangalore there would be lots of puys thr who would want to offload CAT prep. material. Thr is also a thread for this purpose on PG, u can post ur request thr.
