14*sal-10*exp=net saving
we don't know the no. of months on whose basis saving is calculated so CBD
If it saving were avg. saving weres difference of averages then change would be 0% in next question and that is not in the option.

CBD

So CBD for both??

Q. Three camels are standing in a triangular field, which is exactly 100m on each side. One camel stands at each corner; and simultaneously all three set off running. Each camel runs after the camel in the adjacent corner on his left, thus following a curved course, which terminates in the middle of the field with all three camel arriving there together. The camels obviously ran at the same speed, but just how far did they run?

Middle of the field is mentioned so it has to be centroid. Here the height will be ✓3X100/2 and distance from the vertex will be (2/3)X✓3X100/2

=100/✓3m.???

Since it is mentioned far I am assuming they are asking for displacement.

What is the OA?

Puys please try this question

There is a 5x5 square grid,with each of the call having individual identity.In how many ways can 3 identical coins be placed in the grid(one in each cell) such that no 2 are placed in same row or column.

One coin can be places in 25ways.
Second coin in 25-9=16 ways.
Third coin in 16-7=9 ways
So 25X16X9=3600 ways?

In how many ways can 14 different objects be divided among 4 people, two of them getting 4 items and other two getting 3 items each ?

4C2*14C4*10C4*6C3=6*1001*210*20

Thnx @[569305:Faruq] bhai learnt a lot

4 different rings, 2 fingers arrangement matters

5!/1!=120

5C1=5??

@[595020:Erudite.Cat]

The first two are eliminated since the 10s digit is not a multiple of 5

The last one when multiplied by 5 will not satisfy the condition.

The third one 142857 multiplied by 5 does so

142857.

say the weight is 5
Initial value-- 25k
After breaking 4k+9k=13k
Loss 12k
Loss%12/25X100=48%

what are the remainders when 1234567...........979899 is divided by 101 and 1001???

plz share the approach also, i dont know the OA..

DD Bhai a little help from 10 to 99 there will be 99-10+1=90 numbers which will give 90/2=45

And first ten digits will give 1-23+45-67+89=45

So shouldn't it be 90?

@[367896:sumeet1489]

max. 200 scientific
max. 170 graphic
At least 200 total.
Minimum scientific and Maximum graphic
make 170 graphic and 30 scientific. 80 graphic will be sold atleast the rest 90 will give no profit or loss since production cost is not mentioned. I think.. what is the OA?
