Hi Guys,

I am a S/W engineer.
Work ex- 18 months

Serious about cracking CAT nxt year..(appeared this yr got calls from only new IIM's)

DD that i made was payable at new delhi instead of delhi...is it fine?

.how many digits will be there in the square root of a fifteen digit no ???? and also how many digits are there (2ABC)^4whr 2ABC is a four digit number ?????


post the approach ...

for this question u can use this approach
121 sqr of 11
12321 sqr of 111
and so on...
so for 15 digit no. take 123456787654321 whose sqrt is 11111111
in this way the ans will be 8;
Now for the nxt one take 2ABC=2000(i.e ABC=000)
so (2000)^4 will give 18 no of digit .....it becomes so easy after considering:grin: this

Consider the set A = {1,2,3.....,1000}, How many A.P. can be formed from the elements of A, that starts with 1 and ends with 1000 and contains at least 3 digits.
a. 4
b. 6
c. 7
d. 8

here a=1;last term=1000;n=no.of term;d=common difference
now
a+=1000;
(n-1)d=999;
factors of 999
are 1,3,9,27,37,111,333,999
(n-1) can take these all these values except 1;
so n can take 7 values
hence answer=7;

Madhav travels from P to Q that after each of the 20 th 40 th and 60 th minute from the start , he increases his speed by 10 kmph and after each of the 70 th 80 th 100 th and the 110th minute from the start , he decreases his speed by 10 kmph .If Madhav started the journey at an initial speed of 50 kmph and took exactly 2 hours to reach Q , find the distance from P to Q ??????


ans:-115km

plz post the approach ?????

total time taken=120 mins
time speed(kmph) distance(km)
0-20min 50 50/3
20-40min 60 20
40-60min 70 70/3
60-70min 80 40/3
70-80min 70 40/3
80-100min 60 35/3
100-110min 50 20
110-120min 40 20/3

distance=speed(kmph)*time(min)/60
adding all distance we get distance=240/3+40=80+40=120
