24

46080/3840 = 12
3840/384 = 10
384/48 = 8
48/24 = 2
24/2 = 12
2/1 = 2

The number should be 8.

Ans is 384

46080, 3840, 384, 48, 24, 2, 1

1*2=2
2*4=8
8*6=48
48*8=384
384*10=3480
3480*12=46080

isn't this a pattern?


2267

@Torque024 46080/12=3840;
3840/10=384;
384/8=48;
48/6 should be 8 and not 24;
8/4=2;
2/2=1
hence the 5ht term ie 24 is wrong

2268
@Torque024 bhai @grkkrg bhai wala hi kiya hai sme to same ditto

Ans is C
wats C here ?
2270
@Torque024 said:
Ans is 384
Explanation?
2271

Ya, solution may be wrong. I was also getting same.

Some data sufficiency from elitmus:-


1) a tree grows constant height year after year. find that constant height.
a) its initial height was 4 feet.
b) its height after 6 year is 1/4 more than the fourth year

2) In a right angle triangle ABC right angled at B. There is a point D such that BD = DC. Find the length of AD.
a) angle A is 30 degree
b) hypotenuse is rt 3.

Happy diwali to all...quant wale BUMB phootne do :mg:

2274
@albiesriram bhai q.1 mein
intial height 4 toh series aise hgoi
4,6,8,10,12,14,16.
toh 16 at the ned of sixth year toh 1/4*16=4 aur 4th year mein 12 toh yahi hoga solution toh

1) both a & b
2) neither ??

1) yaar if its 1/4 times or feet then it can be answered using 2 alone

2) cannot be answered

1)only 1 statement ie b can solve
2)both statement

First Only B required
For second
both required to solve
